Using iPad OS 16.2 on my Mini 6. For some reason sometimes I am just using the iPad and the iPad wants to shut down. I am not even pressing the top button. I think the shut down screen is activiated by a combination of commands but I am not sure what they are. No I am not doing anything running the unit hot as I am just reading a book or browsing the web. I believe this is either a bug in iPad OS 16.2 or the shut down screen is activated another way but I am not sure how besides pressing the top button. Anyone?
