Sipke, I know exactly what you mean.
Indeed, some things WERE changed. The intentions were good, but these lead to most of scripts that were designed for working with artboards to become flawed. In short, previously Ai allowed only ONE artboard selected at any time. Today, Ai allows many to be selected, to allow pasting on chosen ones ( https://illustrator.uservoice.com/forums/333657/suggestions/32146360 )... but the team forgot to allow scripts to select artboards!

This workaround from 'onthehead' has worked in serval illustrator versions, but since version 29.7 it shows some strange behavior. For example if you copy somthing from artboard 1 and the went to artboard 3 with the script (so 2 times Next Artboard hotkey) and you paste the object it is placed on artboad 3 and 1. Something has chandged in ilustrator and the script places the item two times (the original location and the new location). The scripts from 'onthehead' are still from 2019 and there are no updates available. And since the Admin from this forum (Egor) knows alot... is there somewere else an alternative scipt or workaround in the current 29.8 and 30. Hoping to hear!

Dave, there is workaround I can offer, a free set of custom scripts by 3flab:

Scroll down to View section.
You can wrap these into actions and use instead of native hotkeys.
They are now perfect, but worth trying.
Please comment back if they help and how does it differ from what you want.

Looking for a way to move to the same zoomed in area on each artboard. I work for a major sports apparel manufacturer and use multi-artboards every day. We are make revisions frequently. Artwork is zoomed in to see complete picture because some of these details/revisions are small. Artwork instance is in the same location on every artboard.

There is a workaround we can use, with a set of scripts:
https://onthehead.com/ais/ — scroll down to View section
Display next/prev artboard in center
Display neighbor artboard in center
Display first/last artboard in center

Not exactly that, but does the trick. Unfortunately, this is not that fast as native commands. Still worth trying.

Navigating artboards with hotkeys at the current zoom level.

Yes to navigating artboards at the current zoom level!
