I recently downloaded the beta to ty out and all of a sudden my MCR won't connect to v1.2 anymore, Ive reset my phone several times and turned off and on Bluetooth and even deleted and reinstalled the Movi app and still no success.
You need to keep the app version and the firmware version matched for communication to work. The newer app (beta app is almost always newer than the standard app) can talk to the older firmware, but not the other way around. If you updated your Movi to beta firmware, you can revert to the last stable release from the beta app to go back to the standard version of the app.
