Master Key save my Owner Key

Difficulties to visualise Owner Key

For long time I didn't check my account, finally since days ago I am trying to check if all is good. I was suffering because I didn't find out to visualise Owner Key.
Then, it was also impossible to change Recovery account, for example.

Lucky in an email on 2019 I found the attached document. But still confusing, because two keys were the same, and then I was still missing the Owner Key.
When I read than Master keys allows you to visualise all the Keys, bingo, I found out the correct Owner Key; mistake fixed after 6 years, ha ha.

Well, my account is small, then it would be not a big pain, but the fact to arrive to find out this solution makes a big reward!

Thank you for reading!
