Issue: iPads using square POS not syncing open tickets quickly -- a lag time: We are a winery. In our tasting room we use several iPads with Square POS to check out customers.  Our staff create Tickets (open tabs) on the iPads for customers who want to keep an open tab during their visit.  Customers will often order something at one of the tasting bars and then quickly move to another tasting bar for a different item and want to close their tab at the second tasting bar. When a customer wants to close their ticket and pay, any of the staff can assist the customer using the nearest iPad.  There often seems to be a lag between the iPads syncing the tickets -- for the same ticket, different charges appear on different iPads resulting in incorrect charges and confusion. How can we be sure the open tickets are syncing across all of the iPads in real time, especially during very busy times when we need to close customers tickets quickly, please?  Thank you!
