How about clarifying just what versions should be 'the same' on all the devices?  Mine are all set for auto update and current as far as I know. NONE are the same or even close on different devices.

Droid Turbo 2: v6.8.8

iPad: v3.2.1

Win10 Desktop app: v2.0.2.0

Are you guys just throwing ideas at the wall to see if they stick?  How about not even commenting if you haven't looked at the symptom yourself.  Where is the Verizon Messaging Group?  Can't someone escalate this to get some real constructive help?
