After successfully logging into my account in the mobile browser, enabled sync does not work at all. Trying to check my bookmarks on sync.opera.com makes me see endless loading animation. All saved passwords and bookmarks are inaccessible to me now. The problem is "global" because it also happens on other browsers and on the computer. Can someone explain me what can I do?

@primalvisions My problem solved itself.
