Got a couple of things right off the bat:

1. You might not want your username as the placeholder for the username (maybe you do 🤷)
2. If I click on a pinned post the screen just goes black. In this case, it was this post https://apollo.town/post/22726 when browsing my local timeline

Yeah it’s definitely very busy in terms of the amount of requests that’s get made. I’m not handling a bunch of them that I don’t need but there’s shitloads all the time.
