I started using memrise yesterday after it got recommended. I have been told that it is free, also it says on the web that pro is not needed for using it. Pro will only give you “special” things such as deeper understanding and such.
After making it past level 1, all the other levels have locks on them. I cannot access the rest of the levels and the “upgrade to pro” bubble pops up wherever I click. I have been searching through and read different forums and a lot of people have the same problem, but memrise has not done anything to fix it.
