Force Close the App and Update Software
This is the quickest and most effective initial step to resolve temporary app glitches and compatibility issues with iOS 17.
Many iOS 17 application crashes are caused by outdated app versions conflicting with the new operating system. Forcing the app to close clears its current state, and applying the latest updates ensures you have the most recent bug fixes from Microsoft.
Swipe up from the bottom of your iPhone screen and pause in the middle to open the App Switcher. Swipe right to find the Dynamics 365 app, then swipe up on the app preview to close it completely.
Open the App Store, tap your profile icon at the top right, scroll down to check for pending updates, and tap 'Update' next to Dynamics 365.
Navigate to Settings > General > Software Update on your iPhone to ensure you are running the most stable version of iOS 17.

Reinstall the App and Verify the Environment URL
Use this method if the app continues to hang on the welcome screen, as a fresh installation can clear corrupted local app data.
Collect Diagnostics and Contact Support
If multiple users in your organization are experiencing the exact same crash on iOS 17, the issue may require escalation to Microsoft Support.
