I created a new property, but unknowingly to me it is now a Google Analytics 4 property only by default, and then I noticed that I can't find a bunch of data I used to have like referral path. Maybe it's possible, but I don't have the patience to relearn the UI. Related.

I then learned that I can setup a new property with both the old Universal Analytics + GA4 as mentioned at: https://support.google.com/analytics/answer/10269537 which is what I should have done instead, but is there a way to just enable UA on this existing page so I don't lose the data I've collected so far?
