Mastering Flow Mobile
You can manage your paid licences on the Billing page of the dashboard.
Those licences can then be allocated to your users with the Mobile Access permission.
If you don't have any available licences, you will be unable to assign the Mobile Access permission to the user.
In this case, you have two options:
1. Add More Licences on the Billing page. This is the best option for users who need regular access to the mobile app.
2. Reallocate a Licence on the Users page. This is a good option for infrequent or adhoc users of the mobile app.
