As of three days ago, I can no longer received messages on on desktop. MyAndroid phone and iPad can send and receive. Reinstall did not fix the issue.
The messages displayed in the Verizon Windows interface for my phone are also incomplete, matching the recent outgoing but no recent incoming so the problem may not be the app (which is probably using that interface) but how Verizon is communicating with a Windows environment. Maybe some Wondows update requires a Verizon adjustment.
