Good point, I use UO on Chrome and ABP on Firefox.
Looks like UO is blocking some things, although given the rest of the UI loads I’d expect this part to as well.
It could be Optimizely perhaps. Disabling UO loaded the “Pause membership” link and the “Cookie preferences” one (which I think is something like TrustE). But then re-enabling UO leaves the “Pause membership” link, while still removing the cookies one.
Using ABP instead of UO allows both to load. I guess UO locks a lot more stuff out by default.
