But I can't find where to access them to delete or rename.
I would also like to find out if they are used anynmore as well.
When I look at the page to view hub variables. They are not listed. I can't find anywhere else to look for them
Is this in Rule Machine Legacy? "Global Variables" were used prior to hub variables being available. You can view/manage global variables by clicking directly on the "Rule Machine Legacy" text within the app list.
