Hello,
is it possible to create a new segment and apply it to the data already collected for the last 1.5 years?
We are still using a Piwik 3.11 version which does not receive any new data, but still provides the old data from 2018 and 2019. If possible, a segment should be created there and applied to the “old” data.
I could not find anything in the Manual.
Thanks in advance
regards Ortwin
