I’m having the same issue. It was working the way it should until about 3 p.m. EST yesterday. If I go to edit my profile, then click on Connect, it’ll go to Interactions every time I click on Connect, until I manually refresh the page while in Home. At that point, clicking on Connect reverts back to Mentions. I find it odd, and quite annoying, since Mentions isn’t even the first option, and having it as an option at all seems ridiculous, since Interactions already includes mentions. Any fix to this would be appreciated.
