I have a rather complicated Flow that I want to use as a template to deploy to multiple lists/libraries. I did a "Save As" and made a copy, then changed the trigger to point to a different library (the library is a clone of the one I developed the Flow for). When I run the Flow Checker, it gives no errors, but saving or editing a new document in the target library does not trigger the flow to run. Is there any way to get the Flow to trigger short of building a new copy from scratch?
Here is a little trick which may help you, as you mentioned saving or editing does not trigger.
After you saving/editing, and the flow is not triggered, then edit the flow, simply do nothing and save it directly. Check if the flow has been triggered. In my end it works for a copied flow which does not trigger by item/file change.
It simply happens with some flows using automatic trigger. I am not an expert on flow so not sure what could be the reason, at least it will let you know if the flow is properly set.
