Stopped working after the 7.2 update...Samsung S20+. Disconnects from Sync3 after variable number of seconds. Still fine on S8 that has version 7.1.614574 that has phone screen display. Installed same old version on S20 from apk.... Still doesn't work...puzzled. All battery optimization etc turned off. Troubleshooting steps make no difference (at the expense of losing all my useful cached data). Seems likely that the move to Android 12 has killed it, as reported elsewhere. The "contact form" isn't a contact form, it's just more 'help' info.
