Where is the best place to address specific issues with Lemmy across all instances?

Im consistently running into a specific issue and it is that when instances have no “cancel” button I cannot move back from any post I clicked on unless the text box is completely empty. Having “cancel” as an option seemingly prevents this yet many instances do not seem to include this.

Where this becomes a bigger problem is if I hit “create post” or “share” by accident. If that happens the only way to resolve this is close the page and browser. This is essentially why I almost never contribute posts.

So what community is the best place for this? Fediverse says they aren’t a complaints/bugs forum.

Thanks
