Hi Christian,
I am on Android 16 with a Pixel 8 Pro.
I believe that since Android 16 the quick settings tiles for COL reminder making me a problem.
They are greyed out and so don't react on taping them. After a reinstall of COL reminder they are black and work as supposed, but after a few hours, sometimes a day or so they have turned to grey and no function again.
Is there a fix?
Thanks, Frank.
