Push replication doesn't push updatetd document

Hi, my Android app use replication type push, to sync gateway with couchbase server.

When I create document in database, the replication push the document successfully to The server.
But when I update the document, the replication do nothing and the document in the server stay at the first state despite is continuous =true

Is this a normal fact and this how push replication works.
Or I should use pull_push replication ?

That’s not normally how the push replication works, you should be able to push updates also. You can use addChangeListener on queries and documents to keep track of changes in your database. Can you share the logs and your sync function so I can look into more details? there should be errors in the log if there are any issues.
