Anki - No New Questions After Import

Until recently I have been using Anki on iOS. My set has a main deck with a number of sub decks. I’ve only ever studied from one sub-deck and it has worked fine.

A few days ago I purchased an Android phone, and I no longer have the iPhone. I uploaded my data to AnkiWeb and downloaded to my Android phone. Now, I never get any new questions.

In the sub deck options, I have the following settings :

New cards/day - 5

Maximum reviews/day - 9999

New cards ignore review limit - On

Is there anything else I can change in order to bring back my 5 new words per day?

The timing of you noticing this might just be a coincidence. Is it possible that you’ve run out of available (not suspended, not buried) New cards in that subdeck?
