Question about Facebook backup

I currently use my iPad Air with my Facebook account and all of my characters are backed here. I also have app on my phone but it’s not linked so I never play with this account. Is there a way to link my iPhone game to my Facebook as well? I’ve been too scared to try bc I don’t want to lose all my stuff. Thanks

Anyone???

It can be done, I used to play on both iPhone and iPad. However, you need to be careful not to launch the app on one device while in the middle of a match on another. Also, there have been a couple of bugs with multiple device syncing in the past, but I believe they’re all fixed now.

Thank you!
