@nquateman, you can move it to another computer, but the results are going to be the same. Opera's become severely broken and buggy and I don't know why. I have multiple computers with Opera installed, and they all act the same exact way. The Opera team needs to figure out what's going on, or start building the browser from the ground up on their own again instead of using Chromium.
@neetesha I was only able to see the pre-installed bookmarks after installing Android Opera.
I uninstalled the app, and shut down and restarted the phone. I logged out of the desktop app and reinstalled the Android app. This installation deleted all of the sync items from the sync server but was a "clean" install.
After 3 log in attempts, I finally was able to successfully log in and sync the account. It then took about 15 minutes for the bookmarks to appear on my Android phone. The history and opened tabs did not sync.
. I agree, Opera desperately needs a button to force a manual sync in situations like this. There is a delay in syncing between android and pc with me most of the time but, it does have current sync data when it does sync. Resetting sync will erase everything so I don't think that's what you'd want to do. I would just keep trying logging in and out and hope for the best. It sometimes makes me log out and back on several times before it'll sync anything. It's a pain when that happens, but sync does eventually work.
