All our Workspaces have their Scheduled Data Refreshes disabled

Hi 274188A ,
Thank you for reaching ot to us on Microsoft Fabric Community Forum!

It might be due to a tenant level setting. Check the Scheduled refresh setting in the Power BI Admin Portal ,if it’s disabled or restricted to certain security groups, it may block all users from scheduling refreshes. Other factors to review include workspace roles (users must be at least Members or Contributors), licensing (Pro license needed for shared capacity, only dataset owner needs Pro in Premium/Fabric), data source credentials (missing or invalid credentials will disable scheduling), and gateway setup for on-prem sources. While capacity constraints may impact refresh execution, they typically don't block scheduling itself.
Please refer the below documents for more understanding:

I hope this helps.If so,give us kudos and consider accepting it as solution.
