As Google changed how permissions work in their apps, CanZE had to be updated in order to continue to work on more recent devices. This is why where has been a bunch of releases yesterday and one more this morning.
Symptoms are that the app crashes as soon as the settings page is being opened.
This is because actually CanZE needs the permission to view nearby devices, which a BT dongle is quite obviously 😉
If you want to help, please share any detail about this problem on the following issue:
