Specific app displays error on iPhone despite troubleshooting

I am experiencing an issue with a specific app on my iPhone. The app works normally when I use the same account on another phone, but on my iPhone it does not work correctly and displays an error.

I have already tried updating the app, restarting my iPhone, and reinstalling the app, but the issue persists.

Could this be related to iOS or my iPhone settings, and is there anything Apple can check or recommend to resolve this issue?

I would appreciate any guidance on how to determine whether the problem is related to my device or the iOS system.

Without knowing which app you're having an issue, it's impossible for us to know. If it's a 3rd party app, you should contact the App Developer for support with their app.

If you have a VPN installed on your phone, unless required by a school or employer, you should get rid of it completely. VPN's aren't needed and only cause connectivity issues, often with 3rd party apps.
