I am building an native iOS app with offline capabilites, So i have used smartStore and smartSync. There is an issue when i try to sync same records with 2 devices. Sometime changes doesnot reflect on other device. Like i have 2 iPads A and B.

A has a field package value "XYZ"
B has a field package value "XYZ"

I change A field package to "ABC" and sync it. Salesforce shows "ABC". This is correct.
B still show "XYZ" and when i sync , it still show "XYZ" and now salesforce again shows value "XYZ"

I want the new value "ABC" to be synced on all devices and as well as on salesforce too.
