Pro 3.5 at the time of writing.
I've noticed over the last few months that map notes are really weird.
For example, the layer created from map notes was not viable to be used in a spatial map series, even though adding in the polygons directly was fine (now fixed in 3.7).
Similarly, you can't upload a Map notes layer as a web layer. (Maybe this got fixed in 3.7? I won't be there for at least 4 months)
Today while doing some poking, I noticed the following:
So, why are they set up this way, instead of behaving like a normal layer?
Very interesting find. I’ve noticed map notes behave differently too.
Maybe they still use some previous internal structure, which could explain these limitations
