Information is needed in order to combine data

Facing the same since yesterday, tried almost everything available in KB but, nothing works.

Facing the same since yesterday. It now only works my desktop .

Also have the same issue.  At first I thought it was only a new report that I had uploaded and tried to refresh. However this morning we had some scheduled report refreshes that also failed with the same error. Those scheduled reports have not been touched/changed for months so its not something new that we did in the report...its the system.

Looks like we have similar error message as OP:

A similar refresh issue has been reported internally, so stay tuned.

Same issue here since monday. Our internal support suggested this, but it did not work.

I have the same issue here since monday.

My data are some excel files stored on sharepoint folder online.

The privacy level of those files is organizational.

I have the same problem since Monday. It appears to me as if it's related to the Azure Information Protection label.
Updating unlabeled files still works properly. When applied any AIP label, refreshing will result in error message. 

We have the same Problem. Starting from Tuesday.
Our Data even is directly from Microsoft Graph only and it does not work.
