Account and name issues (Returning player after ~8 years)

Hi everyone.

I recently came back to Mobile Legends after about 8 years of completely abandoning it, and I'm running into a frustrating account issue.

The game won't let me switch accounts or link a new one in any way. Although I already changed my username back in the day, the system is now asking me for diamonds I don't have to change it again, and the account system won't let me properly link my current email or profile either.

I've already tried the usual troubleshooting steps:

* Clearing the game's cache.

* Completely uninstalling and reinstalling the app.

* I also waited out the 5-day period in the account management section, but it turned out to be something else and didn't fix this.

Since my current account is only level 16, I honestly wouldn't mind starting completely from scratch if that helps me solve this mess and get a clean profile.

Even so, I'm still stuck and the game keeps throwing me back into the old profile. Has anyone else experienced this when returning after such a long time? Any solution to create a completely new account and leave this old profile behind?

Any help or advice is appreciated. Thanks!
