@tsteur Guess that happens as multiple id sites and dates are provided. Looking at the code API.getProcessedReport is only able to handle multiple dates. So guess we need to decide if we want to add support for multiple id sites or throw an "unsupported" message instead.

[tsteur]

@sgiehl I believe we wanted to remove that support eventually more and more and have maybe already done partially. I couldn't find the related issue/PRs though. I believe that's for example because certain reports don't work over multiple sites that well when they include forms, goals, custom dimensions, segments, etc. Not sure if I remember that correctly though.
