Hi sidney, first of all sorry for my English, and thank for you post, what you wrote make me to think that i only insist to try on tablet and the second device opera mini on windows phone, but never tried to sync with opera from pc.
I was thinking that it should appear something like folders when i sync on tablet, for this reason i was continuing to inist on tablet only and i read later that with windows phone is not supported yet.
Anyway....with the pc it work very well , i get sync in both , if i delete on tablet then i get it deleted on pc too etc
Thanks for your hint

Ok i have opera on android tablet, i sign in for syncronize bookmark and it there is nothing, thank i know it already. But how i can save my bookmark? I tried opera link too but nothing. I'm tired to try and try
