The One UI 6 Watch update and One UI 7.0 Beta 2 exhibit incompatibility. Calls cannot be initiated from the watch when paired with the phone; call answering functionality is present, but the watch speaker is disabled during calls.
This wasnt present in beta 1. Also note that when replying to a Facebook messenger message from the watch also doesn't work. The watch says sent but it doesn't actually send. Instead it opens Facebook messenger on the phone to the person your replying to but without the reply that was sent from watch.
