Hi @vzdavid,
Sorry for late reply. I did not get any notification about new comments…
NetworkReachabilityManager is not related with sync. This is for handling network connectivity such as wifi.
CBL Java should automatically detects local database record insertion/update, and it pushes new record/update to sync gateway automatically, as your code uses continuous mode.
If you are still having issue, please file a ticket: https://github.com/couchbase/couchbase-lite-java-core/issues
Thanks,
