Hey @BrittanyR
Has the flow been created as a copy or from a template? This type of error/ issue has been observed in such flows earlier. To resolve, you can try exporting the flow and import it back as a package and provide the connections while import and delete the old flow.
You have tried creating one from scratch and that is not working either and I am not sure as to why that is happening.
Note that if you are uploading a file and simply rewriting it over a previously existing file, there a re high chances that the flow will not trigger.
Can you check the above suggestions and see if you continue to face the same issues?
Hope this Helps!
