Thanks for the example Dominique.
I've implemented the sync process based on your example. However, I still
have some issues. I created two document and a user. The app sent the
changes to the sync manager and then to the couchbase server. Now, I
removed the app, installed it again and stopped the sync gateway. The app
started up and I could see in the logs the changes coming from the
couchbase server to the sync gateway, but the problem came up in this step.
If I try to see the changes through the admin interface (SG) I can see them
well. However, if I try to get them from the mobile app, I only get one of
them, the one related to the user document.
Here I copy the logs from SG:

As you can see, the changes attribute is an empty array here. Could you
tell me why is that and how could I get the same changes that I get through
the admin interface?
Thanks in advance,
