Since 81 randomly disconnecting and/or sleeping controllers, only A/B wakes them...

Since my unit updated a couple days ago the controller randomly just drop/sleep and disconnect in multiple games. Toggling hand tracking does not have an effect. Duration before disconnect  is random but happens most often 10 to 45 seconds. Other buttons and triggers have no effect, only A/B wakes them. Doesn't seem to matter how long ago last trigger press was.

Super frustrating, tried changing every setting related to controllers and hand tracking. Changed batteries, rebooted and resetting to defaults also to no effect. No external environmental changes, everything else is identical. 

Extra frustrating because I did not ask for this update.
