Bluetooth and ant+ disconnects ever 10 or so seconds.

Has anybody else had the same issue?  It seems the battery cover issue seems to solve the problem for people whose connections drop a couple times an hour perhaps.... my pedals are fresh our of the box, and can only stay connected to a laptop or phone for 10-20 seconds max. I've turned off all electronics, changed my router to not be on the channel that interferes with ant +, tried both ant+ and Bluetooth, removed the Garmin connect app... All the standard things....

I presume these are actually just faulty as opposed to battery cover related? Any thoughts?
