@skynorth Thanks A lot!!
it was button.hide(), but I had to fill the screen after.
I have tried everything when it comes to removing/hiding/deactivating a button on the touch screen on an M5 tough, searching Google in and out. When I use .fillScreen(), it fills the screen but I can still "click" the button when I touch the screen where it was and then it appears again.
Hoping for an answer to this small question.
Thanks a lot! :D
