Thanks! It appears to be something specific with my admin account then.

Ok, I already see this when I look on lemmy.world instead of my own instance so obviously something is up with my main account for some reason...

Edit: And comments appear fine too. I did have a previous Lemmy instance set up before that I messed up and deleted / started from scratch again where I had the same account name, could it be related to that somehow? Any ideas appreciated!

I'm fairly certain I deleted the VM and started completely fresh.
