I have a simple cloud flow that takes details from a newly created SharePoint List item, and inserts them into 3 separate SharePoint Lists. The 'Create Item' action is pulling all of the correct dynamic content, except for a field that contains multi-line text, which is returned as 'null':

Doing some research it appears that a similar issue occurred whenever the multi-line column was set to 'append changes' but I do not have that setting enabled.
The only thing I could think of is the suggested dynamic content is not correcting pulling the Item ID of newly created item, or it isn't there yet.
I tried creating a separate 'update item' action but it returned the same 'null' value for the Description field.
