Dashboard not loading to Workspace app

I have created a workspace app which has about 5 reports and 6 dashboards.  When I view them in Desktop or PowerBI service they look fine but when I try to view them from the Apps tab on my PC some dashboards appear blank and others have missing tiles and an error that says "Some of the dashboard tiles didn't load". 

I've tried removing them from the app and then re-adding but it doesn't seem to resolve the issue. 

One had missing tiles and then they appeared after a certain amount of time even though all the tiles were pinned at the same time and the datasets being used are small. Any suggestions?
