Instinct 2 solar disconnecting after latest update

Since the latest update my Instinct 2s disconnects from the phone when I get out of range and says “pairing failed”. It will not reconnect with the phone until I go to settings/phone/ (it says “waiting”) turn off the phone setting. Then I have to close the connect app, turn the phone setting back on, it says “open app”. When I open connect again it reconnects. This is happening every time I walk away from the phone for more than 30-40 feet. This has never happened until the past few days. Any ideas? Thanks!
