I recently changed my O365 login and a couple of my Dataflows failed to refresh. I'm getting the TokenExpired error. After reviewing I think these are failing because they use other Dataflows as data sources.
However, there doesn't appear to be a way for me to update my credentials in the Query as suggested in the documentation. I went into the Dataflow and added a table from the same source, and got the warning that adding a new table with new credentials from my Gateway will apply to all tables in the Dataflow (which is what I want), but that doesn't happen. The preview of the new table loads, but the rest of the tables still give me an error. This prevents the query from being saved - I get the "Failed To Analyze Query" error.
Has anyone else run into this??
