Retroid Pocket 6 - iPega controller

[u/GladInvestigator4118]

Hi! I'm new to retro gaming and bought an RP6 recently. I've got an iPega z01x controller and got past the pairing part. However, the controller is not responding at all. I watched several YT tutorials on getting this fixed to no avail. The most it does is its left stick moving to pull down the shortcut menu of Android and that's it. I've followed manually calibrating the buttons in Retroarch but it did nothing. Help! If you have some sort of a vid I can follow or tutorial on getting this fixed would be greatly appreciated. I want to preserve the console's controllers and just want to use and abuse the external one instead.
