Hi Shanmugavel Balu,Could you please share the exact steps to reproduce ?As synch from resolved the issue so does not look like CFP issue.Looking at the description looks like your rfs-1 was out of sync, or sync was not done even once .We can do Webex if needed.Is it a consistent issue or intermittent?ThanksPriyankaHad a call with Priyanka and reproduced the issue, she is going to update after the root causeHi Balu,We are looking into it .I will soon provide update on this.Thank you for going over the issue over webex and showing steps .Regards,Priyankanot seen recently.
