Ankihub not updating new cards

I am fairly new to ankihub but I have tried syncing my deck with ankihub but it was not uploading new cards… how do I fix this?

Not sure what your issue is, can you please describe it in more detail?

I uploaded a deck several days ago and since then I have added 40 cards I would like to chair with my classmate. However even though I have been syncing with Ankihub those cards are not uploading.

You need to add each new card manually with the suggest new note button in the editor (viewable in browse or when making a card)
