UPDATE: during the week of 6/24/2019 (originally 6/17/19), Microsoft Power BI will be switching to using the MSGraph API for OneDrive Personal. Once this switch is made, refreshes will fail for customers who import datasets from OneDrive Personal and customers will notice a “Your file cannot be kept up to date because the credentials are incorrect” message in the Settings page. To correct the issue, customers will need to click on “Edit Credentials” and sign in which will resume OneDrive Personal refreshes. Microsoft apologizes for any inconvenience this may cause our customers.
