I think I accidentally synced devices and didn't want to do so. How do I undo this
Menu > Settings > Unsubscribe .... this will end the integrated messaging
between all devices. If you want to end messaging altogether then you can
also disconnect the device.
Hope this helps! :smileyhappy:
Apparently, some apps are different. On my PC it's "unsubscribe" - it may
be different terminology, but you basically want to stop integrated
messaging. :smileyhappy:
