I have two A9's. One stopped recognizing ANY SQUARE card readers. I have 3 and a new one came in today. The other A9 will not recognize any square card readers. I never tried connecting any before.
This problem started last week. I factory reset the first tablet after going through all of the suggestions I could find to troubleshoot.
I'm stuck with two Samsung galaxy tab A9's that do not any recognize square card readers. These are the version 2 two to pay models.
I have a Samsung galaxy S20 ultra. It recognizes and pairs with the square card reader that the first tablet stopped recognizing.
Something with the tablets is not allowing the tablets to see and recognize the card readers.
