what version that has a working side contact?

I don't know the reason why, but I kept getting logged off from my Opera Account on my browser. In which I would be forced to re-login again and reconnect my flow to my mobile again just so I can transfer files again. It would happen at random times whenever I opened my computer, like it would happen today and the next would either be a few days or weeks.
