As I have stated, my desktop Message+ app synchronization has NOT been affected (yet). One thought I had is my internet connection is thru Comcast service in the northeast (Vermont). For everybody affected, what is your internet service your desktop is using and where are you located? Maybe there is something going on with the communication from the Verizon messaging servers and certain internet providers. Or, maybe there are multiple servers, distributed regionally, and certain ones are affected. Verizon agents, feel free to jump in here with any information being uncovered by the messaging engineers.
