Anki web on my Android phone

Hello I have problem in Anki web the number of the learned cards and the number of the remaining cards etc is stucken it doesn’t change unless after 6 or 7 and it changes from time to time that thing is reducing the efficiency of studying whenever I use Anki web in my Android the number of remainig card stays frozen I so I don’t know the number of remaining cards why?

I’ve seen that problem before. If that’s a problem for you, I’d recommend using the free Ankidroid app in your Android device.

That is good but how could I do syncing from my windows and open the cards on Ankroid ?
