I"m not new to Apple products but would like to get advice and opinions from members of this forum. I'm interested and may purchase this 2nd 12.9" 512gb Apple tablet from a seller on Mercari. but since the tablet hasn't been reset cause it still have the previous ower icloud info. Its still usable and they have tried to contact the owner thru the current icloud email but have gotten no response. If purchase and receive the tablet is it possible for the previous owner to lock out the tablet? Would it be possible for me to try and find the owner using the icloud email to see if they are willing to remove their icloud acct?
