What happens if I forget to renew the POS?

The devices stop selling and show a screen saying the add on has stopped, with a Try again button. They stay paired, your people stay known, and any sale already rung up on a device is kept. Renew from Settings, Plan and billing and everything starts again with no pairing to redo. We remind you thirty, fifteen, seven and two days before the date, by email and on the POS itself.
