Testing in live environment?! This is selfhosted, why the hell not 😂
I'm going to test comment deletion too and see if it'll work. I deleted my comments in another community and to my surprise, not only it's not deleted in other instances, it got a bunch of upvotes and replies too! Going to delete this comment and see what happen.
You may need to edit with [deleted by user] and wait some time then delete or something as a workaround. Interesting to know that delete isn’t be all and all.
Not sure, may need to check the github repo to see if it's a know bug (or an actual feature).
Pretty sure I saw many deleted comments in my instance over the past few weeks, so surely deletion works, at least for some of them. If not, you can always edit the comment and clear the content to simulate deletion. I just edited this comment and I'll see if the edit shows up in your instance.
