Same issue here. I have a large 1440p screen and at max resolution, it's impossible to scale up the UI. Everything looks so tiny. My company gave me a new M1 laptop back in January and I had to do remote work for months on a 1440p monitor with this microscopic UI. It was also my first time using MacOS and got an extremely bad first impression. Really, no UI scaling? Come on Apple, how can you allow this to happen for so long? We're talking about a really basic feature here, and you guys have slacked off for months. This is unacceptable.
