Added a new attribute and the flutter app keeps on returning attributes missing.

If we add a new attribute does that mean we have to delete whole documents and start fresh?

Hi 👋 no, all the previous documents will just have the value from that attribute as empty and you can just normally use them

i got some errors

and i had to delete all the documents

will give it a try and get back to you

Sure, you can also show us the errors you got so we can look into it
