Sorry if I created the thread in wrong subforum.

Neither Opera Touch, nor Opera Mobile see currently opened tabs on my desktop Opera until I start My Flow feature by pressing on the sidebar icon. Then all is working correctly.
Same thing is with Whatsapp. It should sync in the background as soon as I start desktop Opera - as should My Flow.

In short: Opera is not syncing automatically and I cannot figure out why (all flags are set on default).
