I was pleased to accidentally find out about the new Sync system when I signed in to the link page. The new system seems promising, but I'm having trouble.
I migrated my many bookmarks to the new server, and was pleased to see my bookmarks show up on my Macbook. Then they showed up in Opera on my android phone.
Then I made the mistake of installing the Developer edition 34 on the Macbook. When the bookmarks didn't sync, I migrated my bookmarks to the new sync server again, hoping to start the sync process in v. 34. Later, I reinstalled beta v. 33 on my Macbook because of another issue I was having with my keychain (not relevant to the sync problem). Again the sync didn't happen after I logged in to my Opera account. Again I migrated my data hoping to start the sync. Didn't help.
But then I noticed that the Speed Dial page on my android phone now takes 10 seconds or more for my speed dial entries to appear.
I took a look at the migration page again. It shows nonsensical data, such as that I have 21 devices and 495 open tabs. It says I have zero speed dials, but the slowness of my speed dial page populating on my android suggests to me that my 3 migrations have at least triplicated my data on the new sync server.
So I clicked the button to reset my sync data. A message appeared: An error occurred. Please try again later. The same error message has happened three times when I tried to reset my data.
Summary: 1. There are no instructions in Opera or on the Opera site explaining what to expect or how to trigger the new sync system, in particularly that it's supposed to start automatically on login. The sync process doesn't start on some occasions when I logged into my Opera account using beta v. 33.0.1990.35 and developer v. 34. If I'm right that my sync data is now triplicated on the sync server, there's no warning on the migration page not to migrate more than once. If I'm not right about that, why is the speed dial page on my android now taking 10 seconds or more for any of my icons to appear (the Opera version on my android is 29.0.1809.93516, which I've had for weeks and didn't reinstall or anything)? Finally, the button on the sync page to reset sync data doesn't seem to be working.
