I've also encountered this issue for multiple weeks now unfortunately. Would it please be possible for you @Electroid to take a quick look when you have a moment?

For example this UUID returns an old username when fetched via the Ashcon API:
https://api.ashcon.app/mojang/v2/user/e5eca375dfd2499a9f7aa387b906e7d8

And when using the Mojang API it shows the correct updated one:
https://sessionserver.mojang.com/session/minecraft/profile/e5eca375dfd2499a9f7aa387b906e7d8

Thanks a lot for your time and work :)

Hey @Electroid have you had a chance to take a look into this? Unfortuantely the API is still returning outdated profile information. Thanks :D

I don't think he's still actively working on this 👎

@CobbleShop Yeah :( It seems like it.

I can imagine it might just be a caching issue with the worker or something.

I haven't had the time recently to look into this, will try to this weekend.

Really appreciate it, thank you! 😊
