Not at all! The update we recently put out seems to have made some things go wonky... There's a fix you can do to continue playing the game until we have the issue resolved!
1. Click the gear icon pictured in the first image
2. Click on "Manage" shown in the second image
3. Click "Switch to another version" shown in third image
This should let you proceed with the game. I'm super sorry for the trouble-- we're working hard to get this issue resolved!
