Teachable shutting down schools - anyone else miss this?

I received an email today from Teachable telling me I had only a couple weeks to either upgrade my free plan to a $29/month plan or lose everything. I had a paid level (about $450/yr) for one year but dropped it to free because I did not have enough students. I have been wanting to update and move everything over anyway, but now I have a deadline to save all my stuff! If they sent an earlier warning about plan changes, I missed it. So if you are used the free plan, check your email!

Anyone with only a few students happy with a cheaper online course option? I have been thinking PayHip plus Vimeo for hosting. Maybe Thrivecart for its one-time purchase and popularity, but I do not have the money right now for it.
