I was about to suggest what @gnchunter said after just discovering the solution myself, however it seems I am 5 hours too late to be helpful and take the credit on this one :(
At least I put the same solution on the Epic review screen on Google Play – hopefully people would be able to see it and follow the solution before having a moan that the game is broken and it’s all Rovio’s fault! In this case, it’s Google’s!
Maybe free Golden Coins from Google to all affected users as an apology (i.e. all Epic players using Android Lollipop).
