@bb77 I want to understand how are the files/documents sent to the API from the app. and also while updating are the entire files sent or only the differences (between the previous and current) are sent to the API.
Maybe you should have asked that in the first place.
Afaik, synchronisation works on file level, and I’m not a 100% sure, but in that case I’d say, the entire file would have to be sent again after a change.
Anyways, I’m pretty sure, this specific question already came up at some point, and maybe you can find the answer by adjusting your search queries, or maybe someone else will chime in, that can provide a more precise answer…
