I gave both possibilities so I'm not sure which one you are saying I got right haha, I enabled both and got a notification from you so clearly one works. The wording for both sounds like they could both technically apply to any reply or reply to a reply from someone else so I'm not sure.
Ie, if I make a comment and A responds, and B responds to A, both are technically "comments in my thread" assuming thread means all sub comments no matter how deeply nested
At the same time both A and B are technically "replies to my threads comments" (or replies to a comment while being in the thread) so it also meets both conditions there.
Maybe I'm just dense... But I'm going to assume the second one is nested and the first means direct, it feels like I'm trying to decode a logic puzzle on the SAT or something
