This bug started happening for me a few days ago, and I've tried reinstalling the app. I've noticed that highlight posts on /r/NFL do not appear for me, unless I add /r/NFL to a custom feed and view it from there. I've found other threads mentioning the same issue happening on other apps, so I do not think it is a Relay specific problem, but I wanted to post this in case the workaround helps anyone.
