2529211 - Offline OData sync fails with error: -1305(MOBILINK_COMMUNICATIONS_ERROR) error 313 (The operation couldn't be completed. Network is down) (system code 50)

Symptom

When an offline OData application goes online and tries to sync, then fails because of bad network and/or slow response time, and the user retries the sync, it will restart the process instead of continuing the sync from where it had to stop.

Log shows:

An unexpected problem occured while communicating with back end <BackendURL>
WARN Delta download for an Offline OData client failed.
INFO Finished a delta download for an Offline OData client.
WARN An unexpected problem occured while communicating with back end <BackendURL>
