You’re standing at the checkout, or maybe you're just trying to check if that flight refund finally hit your Platinum card, and the screen just spins. Or worse, it just goes white. Total silence from the one app that’s supposed to handle your entire financial life. It’s annoying. Kinda makes you want to chuck the phone, honestly. If your Amex app is not working right now, you aren't alone—this happens way more than American Express would like to admit.
Often, it isn’t even a "the world is ending" type of server crash. It’s usually something much stupider. A weird cache file, a half-baked iOS update, or even a specific setting like Face ID that’s decided to go on strike.
Why the Amex App Is Acting Up Today
If the app won't open at all, first check the obvious. Is it actually Amex, or is it you? Websites like DownDetector are great, but they rely on people complaining. Sometimes a regional outage in, say, the Northeast won't show up on a global map for hours.
Usually, the "server unreachable" error is a lie. Most of the time, the app is struggling with your local data. Since the big login merger between Amex Credit Cards and High Yield Savings accounts back in 2025, the authentication flow has become a bit of a spaghetti-code mess. If you have both types of accounts, the app sometimes gets "confused" about which credentials to prioritize, leading to that infinite loading spinner.

The Face ID Bug No One Mentions
Here is a weird one that’s been popping up in 2026: Face ID. Specifically on newer iPhone models, there’s a recurring glitch where the biometric handshake fails. The app thinks you aren't you, but instead of asking for a password, it just freezes.
If you're stuck on the "Welcome" screen, try this: go into your phone settings, find the Amex app, and toggle off Face ID/Touch ID. Then, force-close the app and try logging in with your manual password. It’s a pain to type it in, but it works nine times out of ten when the biometrics are bugged.

Quick Fixes That Actually Work
Don't just keep tapping the icon. That doesn't do anything but make you madder. You've gotta be a bit more surgical about it.
- The Nuclear Option (Delete & Reinstall): This is the gold standard. Don't just "offload" the app; actually delete it. This wipes the local cache and those tiny corrupted files that survive a simple restart.
- Toggle Your Connection: Sometimes the app hates switching from 5G to Wi-Fi. If you're on Wi-Fi, turn it off and try your mobile data. Amex’s security protocols are sensitive to "network hopping," and it might have flagged your IP change as suspicious.
- Check the Date and Time: This sounds like tech support from 1998, but if your phone’s internal clock is even 30 seconds off from the Amex servers, the security tokens will fail. Make sure "Set Automatically" is toggled on in your system settings.
What’s Up with Android Users?
For those on Android, especially the latest Samsung or Pixel devices, the "Clear Cache" button is your best friend. Navigate to Settings > Apps > Amex > Storage and hit Clear Cache. Then hit Clear Data. You'll have to log in again from scratch, but it clears out the "junk" that accumulates after a software update.
When It’s a Known System Issue
Sometimes, American Express actually is doing maintenance. They usually try to schedule these for the middle of the night (ET), but if they’re pushing a major security patch for the Membership Rewards portal, the app can go wonky for everyone.
If you see a specific error code like "1000" or "OOPS," that’s internal speak for "our servers are having a moment." At that point, there is literally nothing you can do. Put the phone down. Go get a coffee.
The Browser Workaround
If you absolutely need to pay a bill right now and the app is dead, use your mobile browser. Go to americanexpress.com on Safari or Chrome. The mobile website runs on a completely different architecture than the app. Usually, when the app is throwing a tantrum, the website is perfectly fine. It’s clunky, sure, but it gets the job done without the drama.

Actionable Next Steps
Don't just sit there staring at a spinning wheel. If you've tried the basics and it's still broken, here is exactly what you should do:
- Check for an Update: Pop into the App Store or Play Store. If there’s a "Version 6.x.x" update waiting, grab it. Amex frequently pushes "silent" updates to fix login bugs.
- Verify Your Credentials on a Desktop: If you can’t log in on your phone, try a laptop. If it works there, you know it’s a device-specific issue. If it doesn't work there, your account might be locked for security reasons, and you’ll need to call the number on the back of your card.
- Disable Your VPN: Amex hates VPNs. If you’re running Nord, ExpressVPN, or even iCloud Private Relay, turn it off. The app sees a non-standard IP and often just blocks the connection entirely to prevent fraud.
- Wait 20 Minutes: Seriously. Sometimes the server is just overwhelmed with traffic during peak hours or right after a big "Amex Offer" drops.
If all else fails, the customer service line is open 24/7. Just tell the automated voice "Technical Support," and you’ll usually get through to someone who can see if there’s a block on your mobile access. Usually, a fresh reinstall and a password reset are the final keys to getting back into your account.
