This didn't work for me. I was able to disconnect my devices from the online app (desktop) but the problem persists when the desktop was reconnected. The procedure was repeated but Message+ was also uninstalled to see if a fresh install would help, it didn't. An OTT provision error occurred on the reinstall. The desktop app updated a few conversations, but not the most recent one. The online app also looks completely different, being a larger single screen then the tearoff style once from before.
