constant price raising and no flexibility
I am hosting a course since a few years. They raised the Price constantly - so it is getting more and more expensive to host a course. I have al lot of enrolled students - so I can not downgrade my plan and have to pay the full price! But I have not enough new students that the yearly price is worth it. So the different Plan(limits) are really really bad - there are other hosting platforms with way better conditions (which didn't exist at the time I started), but for me its really a lot of work to migrate my course so for now there is no other way than paying more and more.
