Does anyone know if this is happening to them and their stream, or if there's something wrong with my stream?

I followed your stream and submitted an old comment. It featured immediately, so I'm guessing you have one of the top two settings selected in your stream configuration.

Other streams I moderate have new stuff showing up in the approval queue, this meme was one of them :)

Yeah, I switched it over to automatic because the "approval button" didn't show up on my stream. I submitted a test meme of my own and it still didn't show up for me to approve it.

I think the imgflip.com/my-streams page was recently reconfigured.

My second screenshot on this comment is from my "My Streams" page.

Try either reconfiguring your stream settings to one of the bottom two settings in my first screenshot and see if the "Approval Queue" button shows up on your imgflip.com/my-streams page.

Yeah, it doesn't show up. Oh well.

Hmm. The only other thing I can think of right now to try would be if you make me a moderator of your stream I would be able to the stream settings. I'm not sure if that will find a fix, but might be worth a try.

It's okay, I think I prefer it how it's set now.

*able to see the stream settings

When we added Streams Moderated and Streams Followed to the /my-streams page, the link to the Approval Queue was accidentally hidden if you only owned streams but did not moderate any streams you don't own. This is fixed now.

and if you remember the link, you can always visit imgflip.com/approval-queue as well
