Hey! Have you created a formula field that extracts the month number from your date? This will help in sorting months correctly. Same for the production date, create a field to extract the day number. This way you can group per field and sort within groups. 

Hope this helps! 

Actually I have done this.. ive used formula field and datetimeformat allowing me to group them all accordingly

But then the sorting function in the interface wont affect the groups no matter how I arrange them.. 

Sometimes, re-creating the groups can refresh the sorting behavior. Delete the existing groups and create them again in the desired order, does that work? 

Or if this still doesn't work, consider creating a new view with a simpler structure for testing:

Create a new table view with only the necessary fields.
Set up basic grouping by month and day.
Test sorting functionality to see if it behaves differently.
This can help isolate whether it's an issue with your current setup or a broader limitation within Airtable's interface.

Let me know if this helps. 

Hmm, does this look right?  Not sure how your data's set up though

This does look like what I am aiming for, but from what I can this this is a list? 

I would like to make it fork for a "record review" interface..
By all logic, it should work - but it doesnt.. 😞 

You know what - I just tried making a list interface like the one you´re showing - it doesn´t work.. 

Hm, I got it to look like what you want in a record review:

Here are the settings:

I figured out what I was doing wrong.. I tried sorting the groups with the sorting field when I should´ve used the sorting function within the grouping option.. 

Thanks everyone!
