Yes, no problem.
In the test package for 14 days, almost all features of the Pro package are available to you.
But you can switch to any other package and test it for free to see which features are included.
Simply book the appropriate package or additional apps.
If you switch to Essential or Advanced, everything you have created will be retained (course pages, themes). You can then no longer use the features until you have booked the corresponding app or changed your package.
If you leave the package with the "Free trial phase" and book another package, this package will continue to run as long as it is booked. Costs are only incurred from day 15 after registration.
If you keep the "Free trial phase" package, you will automatically be downgraded to the free Essential package on day 15.
