Problem with gamecube adapter for Wii U

[Stache24]

Just recently got the Galaxy S8 and wanted to try dolphin on it. Now it seems to be okay on every aspect except for the fact that when using the included USB-A to USB-C adapter in the box, none of my inputs go through in any game. When a game starts, android asks if Dolphin can use the USB device (the adapter) and I select OK if that matters at all. Any idea what to do? I did set the controller settings to the adapter

Same issue here, but it seems like nobody is willing to debug it.
