How to:
0:20 use the same user
0:40 use the same pos with "Is a Bar/Restaurant" setting activated
1:00 in one POS device/browser open a table, add some product, go back to floor view
1:07 in another POS device/browser open the table. Result: you see added product. You can add other product. Just to remember to exit to floor view to sync updates. POS automatically exits to floor view after 1 minutes of inactivity (it may not work on tablet if it's blocked/suspended before timeout happened)
1:22 if you open the same table at different POSes at the same time, then it will create two orders
