the mythic master account is the 'accountname_uo' one? the EA account name is the one that uses your email address?
i tried that "_uo" in both, recently, didn't work, but, EA at some point in my account fiasco showed Both "acct name_uo" AND "uo_acct name" as seperate accounts (I know because I did a copy/past on every screen in my steps, including Stratics and herald until I got to the end - remember, i have brain damage, and sort term memory loss, so...). Neither worked at any login. Some of the informational steps shown in our "How-To" guide have changed since inception - this includes UOherald too.
IMO, the _uo was the name of the account imported by the migration. They have some serious issues going on, backside. And for those those that have asked in the past, Yes, you can delink associated accounts, don't ask me how tho, but they said I 'did'.
Additionally, some have asked, some wondered, some said WTH, about setting up a "secret word"... The EA Rep here now says said a key can be generated, proving ownership of the account. Marked with a big "
-->" and sent to CS, they didn't acknowledge anything towards that end.
One last Rant... For everyone struggling in your account, once in, if you see UO, warhammer, etc buttons across the top, Don't click them, They absolutely have have Nothing to do with your account(s), and have no business even being there. (they simply take you to the general website related to each game, eg. uoherald). A logo is one thing, why not add ALL of the games you might have an account for with this company? What might that be, 50, 60, 100, or maybe some rotating ads for different games? Beyond Dumb.
