We have to click on “Reset to default” if the screen appears blank when we launch any reports that were shared either via an App or that were shared users directly. This issue was first reported this morning. We have been up and running without this issue prior to today. This issue is unacceptable and needs to be resolved immediately. To all the other users out there experiencing this same issue, please reply to my post and also log a ticket with Microsoft. We logged a ticket at 10:30am EST and still no resolution. BTW, they have told us that no other users are experiencing this issue.
