Hi Experts,
We are upgrading our system from Crm 2011 to Crm 2016. I have few custom lookups on the address page on IFrame. I am facing the following issue. On first time load, the lookups are not populated. Once we re-open the form lookups are working perfectly fine and the lookups are populated properly. It was working fine on Crm 2011 but not in Crm 2016
Need Help. Thanks in advance.
