Thanks for your reply. I am aware of this, however my point was whether there is an option to subscribe to Premium and use the QR code feature in our custom built Moodle App? We would instantly subscribe to Premium if that is the case, helping you to fund the development and maintenance of the Moodle App. We just don't want to switch to the official Branded Moodle App, since we already have development capacities in-house but still would have no issue to support you with a premium subscription.
In my opinion it would bring you more revenue from Premium subscriptions, as I am sure there are others with the same need.
Thanks for your consideration.
