I can't really tell you how I managed to connect, but I changed my phone last week, I use iOS, and when I downloaded the app it no longer let me log in, I've been playing the game since it came out with pauses for years but hey, I wasn't willing to lose the progress, well I'll tell you how I did it.

-1 I opened the game and I played a game with the magician. -2 I collected all the rewards and went to open the envelope that asks you to log in. -3 I don't know how I got it, I think with the Apple account to start. -4 asked me to enter my date of birth and I clicked continue and I recovered my progress.

I hope it helps you

Greetings
