No issues here.

Would you be able to give a brief overview of what your tool does? I feel like it’s perfect for my situation, but am new enough to all this that I’m not exactly sure what the tool does.

Is there any way to see older posts in a situation like this? I created my own instance, and am only seeing the most recent handful of posts from communities I subscribed to.

I’ve noticed the same thing when I switched to my newly set up personal server.
