I am attempting init 2-factor auth going and getting this message: "You can't make this change at the moment This is because we noticed you are using a device you don't usually use and we need to keep your account safe. We'll allow you to make this change after you've used this device for a while."

What is going on there? And is there a way to expedite my ability to make a change? Is there something I'm missing?

This is an account, established quite some time ago, I used to create and currently manage a couple of FB Pages. I'd like to transfer administration of one of them to another FB user but can not do that either. I thought it might be that 2-factor was not turned on which is how I discovered this issue. Otherwise I am able to see what I would expect to see, that is, all seems normal after logging in. Also, I changed my password to see if that made a difference but it did not. Any help would be appreciated of course.

Edit / Addition: This work is all done, necessarily by FB, on my desktop. Cell is not an option at this level as of today apparently.
