From what you've said, it seems like there's an issue with Wear OS 2.1.  If I were you I would just stay with 2.0 until they work out all the bugs....Personally I haven't done an update since the original release of Wear OS, because it made no sense for me to do an update due to the fact that none of these updates are compatible with the Verizon Message Plus App....So, If I can't use the Verizon App on your update...Then why should I bother doing an update...
