After the July 1, 2019 update my app will continuously come up with the screen that says “no controllers” I have to restart my app and the ln it will do it again. Also when I try to go to controller settings all I get is the flashing line and can do nothing until I close and restart the app. I am using an android phone if that helps.
I have my Android team working on a fix as we speak! Sorry for the headaches!
