Hello Daniyal25,
Thanks for using the Apple Support Communities. It appears you're experiencing an issue using the Apple Support app. It's important that you have access to the features this app provides, and we're happy to investigate this with you.
Since this issue first appeared, have you tried restarting your iPhone? If not, please follow the actions outlined in Restart your iPhone.
If the issue persists after restarting your device, you can try force closing the app, using the steps provided in article, How to force an app to close on your iPhone, iPad, or iPod touch.
Should issues continue after the restart and force close, please check out If an app unexpectedly quits, stops responding, or won’t open and give the actions here a try.
Lastly, you may want to power cycle your Wi-Fi router to refresh your connection with your iPhone and the Apple Servers. If you're unsure of the process, reach out to your internet provider or the router manufacturer for direction.
Best wishes.
