I just received some valuable info regarding a known issue on segments. We've identified some compatibility rules that prevented some segments from appearing within Ad Hoc Analysis and Report Builder during our last MR. We're working on getting a fix out, but have not gotten an ETA yet.
If you need access to these segments immediately, we have a workaround available. The segments in question should still be in the Adobe Analytics interface - open up the segment in question, and simply click 'save'. This will recalculate the compatibility and it after a few minutes will be visible in other Analytics capabilities.
Please post here if you're having issues with the workaround, or if you have a similar issue but are not sure it shares the same root cause as this one. I'll be posting updates here as I receive them. Thanks!
If you see "Unknown Segment" or "Deleted Segment" applied to a report that had a segment applied to it prior to the release, then the logic should still be in play and simply 'resave' the segment in the Segment Manager as outlined above. I have also seen this in Dashboards. In Discover it might look like the segment is altogether missing until you attempt the resave.
We have been having problems with Country segments in Ad-hoc. They will not save properly within segments, and I have already re-saved them post-migration. In other segments that include Country as part of the segment, they are constantly forgotten and as such are causing problems when we apply the segments to reports in Ad-hoc. Any ideas?
Adam, if you're able to consistently reproduce the issue, open an incident with Customer Care so they can open a bug with engineering. Based on the information you're providing here, that's definitely not expected behavior.
When creating the incident, be sure to include steps to reproduce the issue so the agent can take those same steps and see that segments are forgetting the 'Country' rule.
