Sorry for late reply. There are red exclamation marks in bookmark, tab. When I checked it my acc log outing by itself. I tried to sign in again but in a minute those red exclamation marks appeared again.

on android (samsung gt-s560)

Yesterday, I decided to installing new Opera Mini (vers. 11) bcs they disabled opera-link for the old one.

I have imported my bookmark from the old one to the new sync.opera.com (It was success).

In the new one, I tried to sign in with my opera account. But I don't know why it keeps log outing by itself. So my newest bookmark (different bookmark from old opera mini) can't sync properly. I checked it via sync.opera.com and my newest bookmark is not there (I assumed it bcs my opera acc keep log outing by itself so the sync doesn't work).

What should I do?
