Fenix 6 pro connect app keeps being dropped and device not on Bluetooth list

Fenix 6 pro connect app keeps being dropped so I have to reconnect..... regularly, this is so annoying.  I have uninstalled, updated reinstalled, reconnected, watched numerous videos on it and it still is happening.  This is after a good few years of trouble free connection... What has changed , getting very fed up with my fenix 6 pro now and the Connect App
