That can happen for a couple reasons I can think of. First, things take a while to refresh in the app, second, a comment was posted and then got deleted. Even with deleted comments, you still get notified. It is nothing new, happens on regular social media as well.

This is happened quite often to me. Also, when trying to leave an emoji reaction to a post or comment you have to hit whatever emoji you're trying to leave six or seven times before it takes.

@Crisalis Yes, that's also another thing that has happend to me. I receive four or five notifications and then when I check it's only one comment.

Yep I have had that happen to me two or three times this week and the thing that I keep getting is that I get like notification every minute that somebody is posted to comment and I go in there and I look and I think there's gonna be like seven or eight comments in there from this one person and there's just one so I don't know if the notification gets stuck or what but I get way more notifications than I get messages and the messages the notifications don't disappear automatically when I've interacted with Ramblio like most notifications too

It’s not just you, more often than not it takes a while for comment/message/etc refreshes to occur.
