Facebook auth broken? At least on community.hubitat.com?

I log into this community site using Facebook login. However, whenever I try now (different browser, luckily this one was still logged in), I get the following when I'm redirected after I login to Facebook:

Annotation%202019-04-15%20193924

When my auth token in this browser expires, I'm going to be locked out of my account, it seems. I used Google auth for logging into the Hubitat Portal site, so I'm good there.

Please let me know if there's anything I can do on my end. I can't seem to find any options to convert this account to an email-based login.
