Friends not showing?

Heya, sorry for yet another post so shortly after each other

I've received a notification that I got a friend, but when I clicked on it, there was nothing. Nothing in the tree house, no notifications on sending good vibes, it just doesn't show anything. Everything should be enabled.

Is this a bug or did I do something wrong?

Thank you for any help <3

Happened twice now, I get the notification > click on it > it sends me into the app where nothing has changed. Googling is unfortunately entirely unhelpful
