Had to temporarily whitelist the page and turn on JS to view (there wasn't even a <noscript> message saying I needed JS). Then since I am in Spain, I got a bunch of Spanish, when I'm an English speaker. This is bad UX. I expected better from FB.
They don't want you to be able to do this, so they make pages unusable.
I tried to delink Facebook and Instagram recently. They make you re-sign into FB via Insta... and it refused to sign me in (I was 100% using the correct password and tried many times). The sign-in just kept failing, until I was like "This is intentional, and Facebook will not let me de-link the apps." and gave up.
Really time for the FTC and DOJ to take Facebook all the way to trial for this sort of stuff. No more settlements!
