Tried this today, and not impressed.
Now that I have activated it, a report I had in the workspace (but not included in the app) in not selectable in the 2) Content - Add Content section (it is a usage report).
Q1 - How do we add content when this behaviour manifests?
I had numerous reports that were in an old app. All put one are now appearing in the updated app. Everytime I go into the 3) Audience section, my report is greyed out and the eye icon crossed. I uncross it, the report ungreys but when I update the app it stubbornly refuses to be visible.
Q2 - How do we fix this behaviour?
Overall, the idea seems good but implementation is not great (apprecaite it is public preview).
Q3 - How do we roll back?
And to Microsoft - when the answer to 3 is - "you can't" - why not?
