I did more checking and it seems like the problem started around June 20th.  It’s hard to be sure because from the log I can’t tell which device the message originated from.  If you can tell me how to determine the originating device I can check more thoroughly.  I send texts from my phone, any of three Samsung tablets, or the app on my PC, as is convenient, and sent messages from my phone appear on the logs on all devices, but messages sent from the other apps do not appear on my phone.

I have a Pixel 2 XL with Android 9.0 with security patch level June 5th and I’m running VZ Msg+ version 6.8.5 on all devices.
