I play on an iPad. It says that iOS12.4.2 software is up to date. When I play on my laptop (Edge) I had to start over. I'm at level 177 there. 

 I beat the level, but after weeks, I am not able to move on to level 426. Thank you, though! Since Crazy Cat Lad is tagged, I hope to hear the solution! This is my favorite game!
