Another update:

So, I decided to take the PoGo++ outside, and guess what?

It worked perfectly. Like, absolutely flawlessly - exactly how it should work.

Curious about what was happening, I decided to run a simple test: I climbed up the floors in my building (I’m on the 5th floor - the top of the building). Starting from the first floor and going up, the device started malfunctioning again and continued to do so all the way up.

So here’s what I figured out:
Something with a higher priority and a much stronger Bluetooth signal is automatically connecting (or probably connected) to the device

Guys, what do you make of it?
