Just wanted to report a quick bug regarding Minecraft IGNs:
It seems that after a user has migrated to Microsoft, and if they change their name, the old name while dropping/on cooldown still resolves to the same UUID.
An example of this is the user "Caves_and_Cliffs", formerly known as "Whomsky". The name history endpoint shows that their current IGN is "Caves_and_Cliffs" and they recently changed from "Whomsky" after they migrated (you can tell they've migrated since the name history endpoint shows milliseconds in the epoch time for Microsoft accounts and only seconds in the epoch time for Mojang accounts): https://api.mojang.com/user/profiles/787e987740234b4eb9a1b93831d19378/names
The sessionserver says the same: https://sessionserver.mojang.com/session/minecraft/profile/787e987740234b4eb9a1b93831d19378
However, trying to resolve the user "Whomsky" gives the same UUID: https://api.mojang.com/users/profiles/minecraft/Whomsky
The same goes for the account "3greatdoggies", whose dropping username "3greatdoggies2" resolves to the same UUID.
The intended behavior is that the old username gives a 204 No Content status code on the /users/profiles/minecraft/ API endpoint while it is on cooldown/dropping.

Just wanted to write a quick update on the bug I reported. The name Whomsky became available (past the 37-day cooldown), but still resolves to the same UUID. The Caves_and_Cliffs name acts as it should when a name is on cooldown, so it seems the bug has been fixed for all future names that will be changed, but "3greatdoggies2" still resolves to the same UUID and is still on cooldown.
We have identified the issue and have a plan forward. The first step will be to allow players to change back to their name they had before they migrated, because we realize this bug has existed longer than the grace period. The next step is to free up the names to everyone.

Hello i seem to have the same problem as after i migrated my account i couldnt change to my old name hope they can fix the issue soon the name (GoldPrestige)
Same for me, I tried changing my name back to Northernside but it says that this name is taken. I got in the migration batch on 24th of August
[media]I migrated my account a couple days ago, and today I can change my name back to my original name. I went to go change it back it says there is an existing profile. I'd really like my original username back as I have people that will snipe it.
unfortunately, it was still bugged until my cool down time was over and someone sniped my name. it’s truly sad to see the name i’ve had for over years stolen, but i do hope this doesn’t happen to anyone else.
Update: Lost my username, it got sniped the MILLISECOND it was available. I'm honestly so upset about this and hope this issue gets resolved so other people don't lose their usernames. I really want my name back but I know I couldn't out-snipe a robot. Mojang has yet to help me with any of my emails I've sent about this issue. Extremely disappointed.
I'm closing this bug in favor for WEB-5345 which better describes the remaining issue.
This bug seems to assume that because our API is returning a profile ID even though the profile has changed away from the name, the name will not be claimable. This is not the case.
Can confirm. This also seems to make me unable to change my name back to Whomsky as it shows that the name already exists.
