Where to find Rotation cap UUID?
Edited
To find UUID of a required cap (capacity), do the following:
Go to Traffic Distribution → Rotation Control.
Locate a necessary cap and click its name.
Note: Make sure you click exactly the cap, as each element in the tree (e.g., folder, advertiser element, cap element) has its own UUID.
You can create a notification to stay updated when a specific cap is full using its UUID. Read this article to learn how.
