Hi @VISHNU_KUMAR ,
So, if I understand it correctly, you create what amounts to Realm’s idea of a “new” device, but using an already existing DB? If that’s the case, it can’t work: Device Sync assumes that each remote device has a different unique id, in order to track which changes have been applied, and which haven’t. Keeping the same local data file, while essentially changing the whole environment around it, basically means that Realm can only discard it, and get it again from scratch.
I may have misunderstood (installing a client in Docker isn’t a usual setup), feel free to clarify the details and the rationale behind them.
