Row Evolution - Some graphs are missing

Hello,

the row evolution function doesn’t work for all types of data. For instance, I get a graph for “Type of screen”, but not for “Mobile vs Desktop”. When I check the single days, I do have data for these days.

Any ideas to investigate this issue? Errors in the aggregated data?

Regards,
Matthias
