Sorry, I wasn't very clear. I'm dealing with the same issue described above that the inherited client tags in a parent project are not propagating down to the child projects.
I had the same issues with Gateway Event scripts and was able to solve this by deleting the folder C:\Program Files\Inductive Automation\Ignition\data\projects[projectName]\ignition\event-script
as described in this thread https://forum.inductiveautomation.com/t/gateway-events-and-project-inheritance-issues/28045
Simply deleting the client tags in the child project as suggested leaves me with no client tags, where as I'd like to actually receive the inherited tags from the parent project so that changes in the parent reflect on the child.
I didn't see an obvious location for the "client tags folder" in C:\Program Files\Inductive Automation\Ignition\ at and it sounds like dkhayes117 and m.cornet had the same question.
