I only started using this app, so that I could respond to messages on my wear os watch. It has been rather frustrating to use on multiple points. I have one person in my contacts that it just won't send anything in the right order to, and mms from another contact that were sent to me yesterday only just came through, plus another contact I sent a mms to 2 days ago, only just received it. None of the online help subjects relate. For a giant tech company, I expected better.
