If user A creates a datadump query, users B,C,D etc who also use and update that same report can not refresh the queries for the sheet.
This is a big flaw as we have many daily reports due.
It should be working. If queries are made in the same spreadsheet queries will be refreshed regardless of the user that executes the refresh.
If for any reason it does not work, please create a new post in the "Submit an error/bug" board with a screenshot or the error that Dataslayer shows so that it can be easier for us to replicate.
