Unable to log in with facebook on new apple device and/or sync with King

Hi, 😊

Thanks for letting me join the Community!

Currently I am trying to set up my new phone and when I try to log in with facebook on Farm Heroes Saga, but I keep getting the error: wrong password and email combination, while in Safari it logs in to my facebook account..

I have tried to see if I can log in from other Apple device and was able to do that from a 13. Mine is 14, but do not see the connection here.

I have already tried many things like checking that the apps and software are up to date, cleared browsing history, restarted the phone, reinstalled the app, etc..)

In desparation I looked for alternative solution and found that maybe I could sync my facebook account with a King account, but what I found on the community that I should look for Setting on the top corner on Kings.com/games, but for me it is not visible.

Would you please advise so I could be able to log in one way or another?

Many thanks in advance everyone!
