In GA4 while reviewing Page Paths, I noticed a large amount of (not set) Pages, with 0 Views but a lot of Users - see screenshot.
I am trying to understand how this is possible, but no additional info is available about the pages (url, title, description - nothing), except for the fact that they are somehow related with the more_than_30_sec event - see last column.
This is an automatic event tracked by GA4. At the same time, the average engagement time is 0s for this group.
So, what could be the issue here?
Page paths / titles etc. are tracked for quite a lot of other pages (there are 292k views).
