Apps deactivate auto lock function
Some apps on my ipads don't auto lock if in use. A previous thread about this question stated that would be the case if the app uses a video function, but this is happening with my Kindle app which shouldn't have a video function.
I've tried the two things I saw suggested for troubleshooting: restarting and changing of the timing of the auto-lock function, with no success. Any other ideas?
Mostly I use this app on my iPad mini, but do use it on other devices as well.
