What’s happening?
Users are unable to enter negative hours in the iOS version of the Microsoft Dynamics 365 Project Timesheet mobile app when attempting to correct a timesheet that has already been posted.

Reason:
The inability to enter negative hours in the iOS app is confirmed to be by design, as the functionality is available on Android and through the web application.

Resolution:
For the negative hours entry issue in the iOS app, users should be informed that this functionality is not supported on the iOS version of the app, and they can use the Android app or the web application to enter negative hours.
