Why did my iPad go back to level one when I was on Level 2171 & it won’t let me go back to 2171

@K7139, which device are you playing on? Apple, Android?

We have a support section here which you can start checking out, you should find helpful steps about synching/connecting the game so progress can sync.

All you need to do is pick the device you are having issues on and follow the steps.

Hope this helps
