Sorry to hear about the issues with the Message+ app on Windows 10, dexman. The Message+ Verizon Messages - Windows Desktop application is not compatible with Windows 10 computers. The Windows messaging client for Verizon messages is being temporarily removed to prevent syncing issues and customers should be directed to utilize the messaging web client as a windows alternative by following the steps listed here: https://www.verizonwireless.com/support/knowledge-base-54302/ Our teams are engaged and working on a resolution although we don't have a time frame to share right now.
