Hi @leandro.freire,
Our Insync 3 licensing is further explained here: Legacy: Prime and Teams FAQs | Insync Help Center
When we had the older licensing model, Plus licenses were available for 1.x versions. There are two options for you to choose from:
- Stay on 1.x: Insync 1.5.7 builds
- Upgrade to Prime so you can continue using Insync 3
To upgrade, click here.
Shoot me an email at support@insynchq.com if you have any other questions
