Please fill out the following sections to the best of your ability, it will help us investigate bugs if we have this information at the outset. Screenshots are especially helpful, so please provide those if you can.

App version number, if a mobile app issue (shown under Settings or About): Not sure.

Description of problem (please provide a set of steps we can use to replicate the issue, and make as many as you need.):

I have been posting lots of observations over the past few days and, as usual, people have commented and identified them. However the comment or ID has not been showing up on the Activity tab, and has shown up as a blurb (but the blurb is marked read even though I’ve never seen it). This is really inconvenient, and I have no idea what’s going on.

Can you please share some screenshots? Without specifics it’s very difficult to diagnose an issue.
