App didn't save progress on 3G

I saw this topic before, but what's the solution? I completed my goal yesterday and I was on a 11 day streak. Today when I opened the app it says I didn't complete my goal yesterday and I'm reset to 0 days. Also weird is that after I got home I completed another lesson using wi-fi and everything seemed fine. How can I get back to my streak? :(

Is it possible that the app is set to not use cell data?

When you got home and did the lesson on wifi, was it after midnight?
