I had 1,820 cloud agents installed before I created my first User Defined Control (UDC). For newer cloud agent installs, UDC manifest is automatically getting assigned. How can I assign UDC manifest to the older 1,820 agents? I tried selecting all in Agent Management and assigning the UDC manifest, but it only applies it on only 20. I also tried selecting smaller subset of 55 agents. Still no luck. How can I overcome the limitation? Thanks.
