I should be able to select any of my Facebook Pages to connect.
Only the 1st page was select-able in the pop up. My work around - because I had only two pages, was to "Connect a different account" after the _wrong_ one was connected. And then my other page was the 1st option the list and could be chosen.
Not a suitable work around for folks with many FB pages (worked for me because I only have 2).

I've replicated it and was reported in 1644089-zen. I'm not seeing any type of console error.
Reported in 1644043-zen. No console errors. User has many pages, so there's no suitable workaround for them.
@blowery is it possible that your PR is the culprit here seems to be the most one touching this component? https://github.com/Automattic/wp-calypso/pull/28607
For the record, this happens with Twitter connections as well. Only the first one in the list of previously added Twitter connections can be selected. GIF showing I logged into one Twitter account but was unable to select that one.
