Exactly!Part of the problem comes from Apple not having a good design solution for when there is too much stuff to display in the menubar. This also is not a new issue, it happened for decades, esp. if you worked on smaller Laptop screens and used more than the few default menu bar items on the right side of screen. Usually menu items from a specific app overlay and hide menu items from the right side - if needed. And these disappear.
The notch should have been reason enough for Apple to finally redesign the menubar and have a solution in place - eg just let users access hidden menu items through some MORE menu. Basically what Bartender does.
So yeah it’s a design flaw - they will probably address in an update - but come on it’s not the nightmare some people make it.
I’ve had this problem since I got a 13” MacBook Pro In 2009. There should just be a “more” button or something when there are too many icons. Same for menu bar items. This has existed in the Windows taskbar for 20 years or so.
Try to use Autodesk Maya. It’s got a ton of menu items and on a 13” MacBook Pro they tend to just disappear.
