The new App experience definitely has a bug

I am using the new App experience and it is horrible.  

I have added new reports to the App.   I can see them under the Audience I have created.    However, the reports randomly disappear.   I have been testing this all morning and it is happening repeatedly.   The reports are there...and then they randomly disappear.   

Anyone else seeing this?   Completely unusuable  (and these are executive reports!).
