Hi Chris,
Thank you for using Microsoft products and making community posts.
I understands the importance of resolving this issue, Don’t worry I will be helping you with this following steps.
- Force Close & Restart Edge
- Double-check that Edge isn’t running in the background by swiping up and closing the app.
- Relaunch it and try again.
- Clear Cache & Cookies
- Open Edge, go to Settings > Privacy and clear cache/cookies.
- Restart the app afterward.
- Disable Extensions
- If you have any extensions installed, try disabling them and see if the issue persists.
- Try Using Private Mode
- Open Edge in InPrivate browsing mode and attempt the transaction again.
- Check Payment Site Compatibility
- Some websites don’t play well with Edge on mobile. If possible, try making the payment on your PC instead.
- Reinstall Edge
- Uninstall Edge from your iPhone, then reinstall it from the App Store.
Please feel free to let me know how it goes.
