Ah yes. I forgot to link it. https://github.com/happieio/typeapp I just updated it to link to cordova-android@5.0.0 to support marshmallow. I have been doing these tests on marshmallow, nexus 5x. I am getting the same results in this test app. I sent an email to the one listed on your github account with the sync gateway url .
you can replace the sync gateway url in the app here https://github.com/happieio/typeapp/blob/master/src/lib/data/db/api.ts#L64-L65
the initial view has a two way replication button toward the bottom.
Side note the typeapp repo is a submodule within the couchbase-lite adapter repo.
