In order to set the permissions of the Ebriza POS application, you will have to follow the next steps:
Go to Apple Device Settings
2. Scroll down until you find the list of applications and select the Ebriza POS app
3. From the list of permissions, make sure that all the options are checked (especially the “Local Network” one on iOS 14 devices)
If the device on which we use Ebriza POS has an older version of iOS 14, we just need to make sure that "Notifications" is checked "Allow"
