I was able to sync my data before, and I could see my data. But now it stopped, and when I visit sync.opera.com to view it, this message pops up: You have no sync data stored.
Sign in to Opera to start syncing, and access your bookmarks and other browser data from all your devices.
I am signed in on both Opera and Opera Mini for Android, and they did sync, and I could view my data and everything there, but I am NOT able to do so now.
When I go to the synced speed dials/tabs on Opera, I see nothing at all. I am running Opera 56 on Android 7.1.1 on Samsung Galaxy Tab A. Even creating a new account didn't help. I tried signing in and out repeatly and using both accounts, but I still can't sync. I can't even reset my data as the same message pops up when I do, preventing me from doing so. Everything expect my bookmarks are yet to be synced so far. How do I make it sync again?
UPDATE: So, it did sync now, but only partailly. My bookmarks and speed dials did not sync, only my tabs.
UPDATE 2: It finally worked! You are free to lock this as the syncing is now working.
