Dear jav6 (Sr. Member),
I'm glad your desktop environment allows Message+ to continue syncing for you.
Unfortunately, your testimonial provides no solution for me or waywardfarm (Member) here,
or cratervoid (Member) or csorb (Member) or DStan (Member) or wefuwf (Member) or david_arnesen (Member) or ptoundaian (Member) or Kikov (Member) in this other thread [https://community.verizonwireless.com/t5/Verizon-Messages/Message-Plus-not-syncing-with-windows-10/t...].
Perhaps you could help identify how your Windows environment differs from all us other members who DO have this failure?
Mine, as well as the others, "was working fine" for years (in my case, at least), but stopped working just recently.
What version of Windows 10 is your Messages+ app working fine in?
Are you using an Anti-Virus app?
Are there any skilled Verizon Messages developers who could use the differing details to figure this out. Or even care about those of us who want Verizon Messages to work for us too?
