Course synchronization

Hi,
My account on PC is not synchronized with my mobile - while in my mobile I'm in a phase of learning a "new word", in my PC I left with some previous phases behind.
So my question is how do I synchronize between these two versions, so I can have an access to my proper level from both of these versions?
I didn't find such an option so far, which leads me to post this question..
Thanks in advance!

I think this is a bug they've been working on trying to track down. The advice in the meantime has been, for a given day, to only use one device that day. Next day is OK to switch. That's what I've been doing. If I start my daily work on my phone, I finish it on my phone, and vice versa.

Looks like your connection to Home was lost, please wait while we try to reconnect.
