I started using Vivaldi when they finally added sync a d the sync is a thing I have the most problems with!

I randomly get duplicate notes and bookmarks if I edit some.

It always feels like ages until things get synchronized between devices (e.g. tabs).

There’s this very prominent button in the share menu “Send to device” which doesn’t work at all (I’ve read somewhere that it’s a deprecated thing from Chromium, but why haven’t they removed it for several years it’s broken…?)

And also in past months it just randomly disconnected from the server several times on several devices, didn’t even notify me except for changing the sync icon (on Android you have to go to the settings menu), and for a reconnect, I had to enter the passphrase again each time.
