@isinha (sorry I am unable to reply to your answer directly as a comment, it allows me to type my reply but the "Comment" button does nothing) I'm not sure how to see the Scheduled Projects Manager UI. Yesterday I tried twice and both times I got the error message by: 1. Opening the workspace. 2. Clicking share in the menu. 3. Clicking "Send file on schedule". 4. Adding the recipient (I am already a recipient, and the person I'm trying to add also used to receive the report until a week ago or so). 5. Choosing a start date and time in the future - next Monday at approx 6.30am (the end date was already set at approx 1 year in the future, so I didn't change that). 6. Clicking "Send file on schedule". 7. Error message appears. Today these exact same steps have worked and it has allowed me to schedule the report successfully. I guess this might have been caused by maintenance or system downtime yesterday maybe?
