As of v 2.3.2 this (panning with the mouse wheel), like many things in Pro, is half baked. Still feels like some kind of Alpha release. The behaviour is inconsistent and flaky. Sometimes it works, other times the middle button is not responsive until the explore tool is clicked. We are almost entirely migrated to pro and forcing ourselves to use Pro for everything (90% of the time) but when doing heavy duty editing, clipping, merging copying and pasting of features between layers, the experience is one of constant frustration with so many bugs and glitchy and strange behaviour. Only going to ArcMap when necessary but it is very much still necessary. Whenever I go back to ArcMap it amazes me ho fast and reliable it is. It may be old, it may be 32 bit and on a single thread but when it comes to editing, Arc Map is still the king. Designing the entire editing process in Pro should not be left entirely to programmers and people that do not actually spend days and weeks editing complex geometries.
