I can't log in with my Facebook account- Under Investigation!

i just switched from an android to an apple phone tonight, and i was trying to set up my candy crush friends app by logging into my account through facebook (which has always been my form of logging in for years now) but when i went to connect/sign into my facebook i got a notification saying that the app was not set up and is still in development mode, etc. i tried several different ways of logging in, i went to my facebook app and it still said the status was active...i googled it obviously and tried several different ways to login through my facebook and nothing worked. and then i read somewhere, which i wasnt too sure about trying this method, to go on my facebook and remove candy crush friends from my list of games i gave permission to login with...so with trying everything i knew to try, i ended up deleting it off my facebook, hoping that i would just be able to log back in and give it permission all over again to use facebook as my login....but the outcome of that didnt change anything and now im scared that ive lost all my progress ive made in my game, i think i was near almost level 1000, so ive made a good amount of progress to just give up and start from scratch. is there anything i can do to recover my account and not lose my progress ive made?

Me too! On android phone and Android tablet. But my error says "there was a connection issue. Try again later". I am having no connection issues and other games connect fine.

cannot log in through facebook , I do not know what is going on grr

I cant sign in on my Facebook account says it in testing stage & I don't have permission
