1.2.1- Replication issue with Android and couchbase sync

[Stephanevincenza]

I've installed releases 1.3 for IOS and 1.2.1 for Android.
With the same code to start replication, I have always the same ERROR on Android.

[ERROR] : Sync: com.couchbase.lite.replicator.ReplicationInternal$4@424eece0 checkSessionAtPath() response: {authentication_handlers=[default, cookie], ok=true, userCtx={channels={!=1, _=218}, name=_**}}

The strange thing in the log of Couchbase SYNC ....

*With IOS *

So, it seems that the two version don' t work the same way.
IOS gets the changes and then write a local file on the server (probably the session id) while android first tries to get on session id, then a local file, and then gets the change. And never find the local which is created after replication by IOS !!!!

I don't understand anything. Why is the replication transaction so different between the two platforms ?

Really need help .........
