reset ipad with findmy on without id
I let a family friend use my old iPad Mini 3 and now I am unable to get it to reset because they are unable to remember or find anything to do with their Apple ID. I would like to use this thing, but since FindMy was turned on before it was reset, I cannot.
How do I get this fixed? Is there anyway other than taking it into an Apple store and having it done?
