I was trying to change my display name to a new one, and foreseeing questions "have you accidentally tap 'reset' button?", no, I haven't. That name was accepted, it was visible over my avatar and in my profile feed (you know, those "has changed their name" system messages).
But later my friend asked me why I have only username visible and weirdly I noticed one more "has changed their name" message in profile feed right after 14 minutes after I changed name. I swear I never used "reset" button. I had no reason to use it.
So here's the question how that even was possible? I know I can do nothing but wait a week to get my name back, but I'm curious about reasons for that :c
