Both Opera for Windows and Opera for Mac have the same settings regarding sync? After the synced data reset, did you change the passphrase or disabled it in settings?
I am joining the group of unsatisfied Opera users on Mac running Mojave. Version 56.0.3051.116 and this bug is still not fixed. Can somebody do something about it? It drives me crazy and obviously other users too. Thanks? ...
Did you ever receive any feedback on this issue? I believe mine was working a few weeks ago and now it is not... Quite a pain to be forced to hit F11 to see ALL windows every time I want to switch active windows. (So much of a pain I'll be forced to switch browsers if I cannot find a solution.)
