8BitDo SN30 Pro+ controller face buttons mapped incorrectly (same issue as Switch Pro Controller?)

Thanks for putting this on our radar, Tenno! We have the issues with Nintendo Switch Pro Controller on our Known Issues list, and as you theorized these two may be similar. 

We cannot guarantee compatibility for all third party game pads, though it's possible that when the Nintendo Switch Pro Controller issue is resolved, it will improve the situation with your 8BitDo as well.
