hold on.
connecting after pairing?
try this. follow these steps exactly.
open pogo. eject go plus.
close pogo. go into bluetooth settings.
un-pair go plus (it should not show up, but if it does, we found a problem.)
turn off bluetooth on phone.
long press go plus until light stays blue.
long press until vibrate.
restart phone.
once restarted, open pogo (Bluetooth still off)
when pogo is open and running fine, turn on bluetooth. (best would be via drop down settings menu)
go into settings in pogo, go to go plus.
there should be no devices at all. if there is, eject, and restart this process.
only when you are sure there is no go plus connected, or paired to the phone do you click the button on the go plus.
the light on the plus should flash white.
now there should be a go plus icon in the game that you can connect to.
I suspect the reason for your struggles is your phone is pairing to the go plus before pogo is connecting, leading to some funny settings coming from the game.
if you connect at any time, remember, the go plus will vibrate within seconds of you telling the game to connect it. if it does not, and you find your plus has a green dot under settings, but no green dot on the home screen, that is what is happening.
force closing the game and retrying without shutting down solves that reconnect issue for me about 50% of the time.
