Daily study schedule and formatting lecture sub decks into subject decks:

Hello! I have recently started using Anki and noticed that a new deck I made yesterday isn’t giving me any cards to study today. I checked the ‘start next day’ time at its set to 4AM, so I don’t think that setting is the issue. Also, I have made a new lecture sub deck and dragged it into a subject, but Im unsure how this affects my study schedule as the cards are added to both by ‘Anatomy’ deck and my ‘gluteal region’ deck’. If anyone could help that would be great!

You appear to have new cards waiting now - did you resolve the problem?
