iOS 13.5-13.6 doesn’t support game controller Bluetooth connection

Dear to whom may concern,

my Flydigi Wee2T Bluetooth game controller doesn’t work with iOS 13.5 or 13.6 at the moment, I can’t play any online sports game with my friends now, could anyone tell me if there’s a way to reflect this issue? I can still connect it but it’s not detectable inside the game or the testing mode. Please help me out, thank you very much!
