The update/Companion App drained the Battery during regular smartphone use from 100 to 88% in about an hour.
So, I performed a "forced Stop" of the App, and left its unused for a couple of days. Battery usage has restored and..as a side-effect, the BT dropouts were less as when the Companion App is in "active State"....
I would advice everyone who uses Android to only connect your Ha's with Bluetooth and leave the Companion App for a Trail..
