Up to yesterday, when I 'Test as role' and view a report a menu shows up allowing me to select multiple roles, now today this menu is missing, therefore I am only able to test one role at a time.
@v-qiuyu-msft Tested it just now....still won't work. When I did it yesterday, it showed just like your screenshot....but today when I try...the bar with 'Now viewing as:' doesn't show.
