Can you mix Android and IOS tablets for scoring a match and sync them all back to a single tablet without issues?
Yes, you should have no problems doing it.
Yes, this is almost a normal routine for us some days.
Last week we had a minor crisis when somebody didn’t charge the regular Android tablets we use for the matches overnight.
We managed to come up with 3 iPhones and two Android phones and they all synced up nicely at the end of the match to the Master tablet.
