This issue seems to still be around. I checked my pinboards this morning and all of them (20+) were just gone, even though I didn't use any system cleaners nor did I install or change anything vital about my system. As it happens I even had synchronization turned on as long as I've been using Opera and it didn't help whatsoever. I even have a bookmark to my pinboards page and it also leads me to an entirely empty pinboard section.
As many other users already stated here in this thread I'm pretty disappointed, I also saw the Opera pinboards as a great alternative to other note apps and extensions but such a substantial bug is completely unacceptable.
I'd quite mission-critical information stored in some of my pinboards, lost everything now and I know that it's kind of my fault because I didn't back up that information elsewhere but stuff like this simply shouldn't happen.
In addition, you're not even able to back up your pinboards in any comfortable way and backing it up by copying it to another file isn't just as easy as CRTL+A, copy and paste it into that file. Every time you want to do a backup you have to click into every single pinboard headline and text field manually, which is extremely tiring, at least for me.
All in all, I think:
- Such a major bug/issue should've been patched as soon as the first person reported about it, it shouldn't be a thing even months after a forum thread like this one was opened.
- You should be able to backup your pinboards to a specific file of your choice.
- Synchronization should just work and save all of your pinboards.
- If stuff like this has happened you should be clearly notified/it should be understandably stated somewhere before using such a broken feature.
In case someone found a way to recover your pinboards somehow, I would be more than happy if someone could contact me or answer my post here
