I try to log in to square.  It starts to process and then stops.  I get a message that the process has stopped and to try later.  Can't get the square to work.  Need it for tomorrow.  Help appreciated.  Thanks

If all else fails, delete and reinstall the app. The only information that could be lost would be offline transactions that have not yet been completed. Otherwise, you hopefully can sign right in and start selling.
