I'm seeing a lot of local communities that have very few or zero posts showing up when I click on them. I noticed this after I posted yesterday and got a few answers to my post, but when I go to that community my post doesn't show up. The sidebar says the community has 80+ posts but I can only see about half a dozen and they are all 1-2 months old. I have checked some other communities that I've seen posts from in my feed in the past, and now they show completely blank, even when looking at Old. What's going on?

I'm seeing this in two different browsers (Firefox and Edge). I tried clearing cookies in Firefox, no difference, and I had never used Edge here until I tested it out today, but it shows the same problem.
