I have been using a Note 4 with a Gear S2 and Message+ and prior to the update I was happy and they worked well. Since the update I do not get notifications on my watch from other Message+ users. I narrowed it down to the Gear app needs to allow Message+ notifications since they don't come in as SMS or MMS, but are "chat" using data. When I do that I get a notification of the message, but am unable to reply directly from the watch. Additionally, the mute function no longer works for any of the message threads which is the reason I started using the app in the first place. I have been forced to go back to the factory Samsung messaging app which also doesn't mute, but at least my watch works as it should.
