After a long wait and discussion with the help desk, I finally had help from the developers to solve my problem.
The theme is good, it has good functionalities, but I suggest you evaluate your LMS system, it is extremely basic compared to others on the market that have functionalities for interaction and course management between instructors and students, even in the free version.
You should also have a team of developers ready to help the help desk, to avoid your customers waiting 20 days for a problem to be resolved.
The price you are demanding for your theme is not adequate for what it offers.
