Looks like the same issue as this: https://forum.mendix.com/link/questions/109046
It seems to be an issue with Xaomi devices probably related to:
https://github.com/wix/react-native-notifications/issues/287
There is a suggestion in there about a code change that could be made. You’d have to build a custom developer app to try it though.
I’ve raised a support card with Mendix Support.
Today, we released the new version of the Make it Native 9 app (version 1.2.12) which includes the fix for the android.os.UserHandle issue on Xiaomi devices.
(thought it would be better to post it on all related Forum posts I could find)
