I don´t see any problems like crashes or that the DAU number has changed, but App Store Connect shows 3 times more deletions since the release date of iOS 13. Now I don't know if there is any problem in the App or if Apple has made an upgrade of the "App-Offloading" mechanism? So it would be good to have some feedback, if the app deletion numbers have changed for somebody else as well.
I have that message in App Store Connect:
App deletions data was reported incorrectly for iOS and tvOS as of August 2019. This data has been removed from the dashboard for reprocessing and will be re-enabled once reprocessing is done.
