Is your Yahoo! account receiving messages from other sources?
Yes I am receiving all other emailsIs your Yahoo! account receiving messages from other sources?
That is what I thought originally, unfortunately I can't even access Yahoo technical support because you have to pay premium to speak to an actual person.My only thought is that maybe it takes some time for blocks or un-blocks to actually take effect. But if you removed the block a week ago that's not at all likely the problem.
I had literally just added it as a blocked addressHow did you block emails from Facebook?
The strange part is that I do have two factor authentication fully set up and I have used it many times, I can see all the settings on it on my phone in which I still have access through the app, I just cannot get it to connect with my laptop despite having worked beforeYahoo says the sender isn't notified of blocking.

Unfortunately there's not much you can do to access Facebook if the automated recovery process doesn't work. I think there's a manual process, but that will probably be delayed right now due to COVID-19.
If you get account access back, change notification settings in Facebook instead of blocking emails in Yahoo, and set up 2-factor authentication.
