OLO Shows Store Close/Order Gets Cancelled if POS isn't in the foreground

We have an iPad POS. When the POS is not running in the foreground (e.g. Safari is open and we forgot to go back to the POS screen WITHOUT terminating the POS app). After 5 minutes, the POS assumes the store is closed and it shows on the OLO that it's closed. The BIGGEST problem is this scenario; 
1. a customer orders online when the OLO shows store open (meaning the POS is running in the foreground). 
2. For some reason, an employee opens safari (as an example) on the POS and forgets to return to the POS app (so the POS isn't in the foreground) and it is not terminated. 
3. Customer receives a cancellation email and we LOSE the customer and the order. 


It does NOT make sense to show store is closed and cancel customer's order just because the POS is not running in the foreground. This shouldn't happen and we should be able to still receive orders and also the order gets automatically printed. I have never seen this in any other POS system. This is just a common sense. No matter how we tell employees to keep the POS running in the foreground, sometimes they just forget (e.g. they want to print something from safari or whatever the case is)> 

on phone as an example, you don't stop receiving notifications if you texting app/FB/IG or whatever is not running in the foreground. This is just a common sense.
