So you want Glide to do something that , Amazon, Google, Netflix, Apple, Microsoft, Banks, Wont do. Hmmmm.
Once a customer has purchased something, whether digital or otherwise, by law they have the right to share it with anyone who they desire. They are now owners of the content. They are not allowed to duplicate it or resell it however. Unless by logging in to multiple devices it jeopardize the content itself.
Most people have at least 3 devices that are synchronized across platforms. 1. Their phones, 2. Their Tablets, and their Computers. To cut off peoples ability to sync workflow between their devices would cause you to lose your customer base
No user wants to be controlled or limited like that on free apps, let alone on content they pay for. Netflix tried it 10 years ago and it didn’t work.
This is why Netflix, instead of wasting money to trying to stop people from sharing account, instead they helped people to share premium content by setting up individual sign ins to the same premium content. This helped their user base to quadruple and sales went up.
No one can or should stop individuals from sharing premium content with or without session management. Its a reality every content provider has to live with.
Glide has to be careful in how they implement this as they could be violating its own terms of service regarding who owns content and limiting content. https://www.glideapps.com/legal
Its not legal to intentionally limit access to an individuals own paid content.
