It’s been a long time since the 3.6 release, maybe your devices weren’t in the mapping yet. If you want to check, here’s the mapping file from 3.6: https://github.com/MonoGame/MonoGame/blob/v3.6/MonoGame.Framework/SDL/gamecontrollerdb.txt
So yeah, switching to 3.7 will get you a lot of bugfixes and support for more joysticks.
I’m not sure actually.
