After a year using this app, I still can´t figure it out how the exact steps I have to do to get to sync speed dials between my android phone and my tablet. I created my account, and being looged on both devices, I only see old syncs of my other devices, sometimes devices appear more than once with different sync dates, and it is very difficult to get the current list of speed dials for each device. I log off and sign in many (too many) times until it finally "works"; but it is a real pain that this doesn´t work in a more straight forward way... or maybe I am missing a step or doing something wrong... please can somebody help me to understand how this feature really works?

Thank you very much!! Turned out that in Opera official site version 47.xxxx is still available for download, so I did what you suggested and I am back with a more stable version, thanks again!!

I recently updated to last version of Opera 48.0 and I realized that some web pages I usually visit are not displayed properly. I already sent a bug report, but I would like to restore to the previous version of Opera while this bug is fixed, please is any way I could do that? Thanks in advance, and regards!

Thanks to you and @campedor92 for all the feedback for this issue, I seem I have a similar problem, and trying to follow your comments, I am still not clear on how to proceed to get bookmarks and speed dials (specially these last ones) synced between mobile devices (phone and tablets) and Desktop PC.
As far as I have tried, I have had to toggle sync enabled/disabled and even manually sign out/sign in to (not always) get speed dials synced. But when I try to see speed dials from other devices from my mobile, they don´t appear and even sometimes they got erased!!
I will try to set sync options as campedor screenshot, to see if teher is any improvement on this issue. All my devices have Opera beta installed and updated, but my android devices have different OS versions, being 4, 7 and 8 each.
I would be very grateful if you could give me more input on this topic, because it takes a lot of time to get sync between devices and I am stil not clear which are the best/direct steps for this, thanks again and regards.
