@Benjamin Kokholm Broen, Thanks for posting in Q&A. For the apps DataWedge, DWDemo, StageNow or Play Store which we deployed in kiosk mode. I suggest set leave kiosk mode PIN and leave the kiosk mode on the device and try to open these apps on the Android devices to see if they can open to clarify if the issue is on these apps.
For our issue, please also check if the issue occurs on other Android devices with different manufacture. Or if it only happens on one device.
If there's any update, feel free to let us know.
