I have a custom segment with a filter which compares the beginning of a campaign name to a string, which worked nicely under 4.6.2.
But now in 4.9.1, it is not possible anymore to select any campaign properties to filter segments. And all my old campaign based segments now produce error messages.
Am I missing something or has this crucial feature been removed?
I was able to create any segment which did not involve campaign based values.
When I tried to select the campaign based segment, the dashboard showed me messages, that the query may take too long and that I should contact the admin (myself). Upon closer inspection, I saw that now all segment variables have disappeared and are unknown.
Unfortunately, I do not have any logs and I reverted back to 4.6.2 to use campaign name segmentation.
Was this feature removed on purpose or is this some kind of bug?
Or an IUE (incompetent user error)?
