Can't log in on my phone. RESOLVED

I woke up this morning and went to check out the daily puzzle, but I had been logged out on my phone. When I went to log back in through facebook, it said "Invalid Facebook Access token" and wouldn't let me in. I went through the forum and found followed this recommendation, it did not work. I still get the message. I am honestly afraid to sign out of my account on my computer in fear that it won't let me log back in. 

I went to "Apps and websites" in the Facebook settings, and Chess.com is still active, so there shouldn't be an issue logging me in. Someone please help!!

Did you uninstall and reinstall the app?

Also having this problem and did the same recommended steps.

Just found out that is something that is apparently being retired.

You'll need to contact support directly to help. They'll need to add an email and password to the account as I understand it.

Actually, disregard my last post. Apparently this is fixed now 

Thank you to everyone who commented with advice. It seems that the bug has gone away and I was able to successfully get into chess.com on my phone.
