UNKNOWN ERROR WHEN TRYING TO LEAVE LEAGUE

@EA_Blueberry i also met same error, and it is still not work after doing your advise.

@kylelindragon

Can you DM me your User ID? It's found under Settings in the top right corner. It's the number.

@EA_Blueberry thanks! I DM my User ID to already.

@EA_Blueberry I am sorry that my poor english make me confuse what you said. I guess you are asking what I had done before the error appear?
I didn't do anything, only that I gave up playing the game for two or three years already. I returned at about one month and half ago. while at the beginning, I didn't know I can't leave my league until I playing event that told me to join the league. When I try to leave the league, system told me should pass leader to others, but I can't do it either. After that, I started to kick out others who don't play the game anymore either. Finally, there is no one but me in the league. And then, the error showed up.

Thank you!

Do you know if anyone else can get invited into the league and you can pass over ownership?

@EA_Blueberry no, whenever someone invite me to join his league or ask to join my league, it only show in the mail. But I can't see anything at the page which is for managing agreement of joining the league.

@kylelindragon

Can you try updating your EA profile name at profile.ea.com and see if that has any effect?

@EA_Blueberry you mean actually name or EA ID? I can't find other profile name to update.
I have update my actually name, but there is no any effect.
