Thanks everyone for standing by on this concern. We’ve got an update from our Internal Support and the following steps are suggested by them that can help in addressing this concern about the crashing of the PowerPoint for iOS. Please see these:
- Close all the Office for iPad apps. To do this, press the Home button on your iPad twice, swipe to find each Office for iPad app, and then swipe the preview screen up to close each app.
- Go to iPad Settings.
In Settings, tap to select one of your Office for iPad apps such as Word, Excel, or PowerPoint.
- Under RESET, tap Reset <app name>. (Word for example)

- Slide to enable Delete Login Credentials.

- Start one of your Office for iPad apps (PowerPoint) so that your credential is deleted.
- Sign in using your Microsoft 365 Organization ID account.
Once done, please check if the PowerPoint for iOS will still crash so we can have this reported back to our Internal Support for further investigation.
Please respond to this thread to let us know how the issue progresses. Similarly, if you have more questions, please inform us by replying to this post.
Best regards.
