I can relate in so many ways. I purchased a MX Master 3S and while it has a lot of great design choices, overall there were too many flaws for me and I returned it.

While I had the mouse, I kept looking for ways to "fix scrolling" and everything repeatedly pointed to third party software. If you have an iPad or Android device, you're completely out of luck.

How does a company become so out of tune with customers that customers feel the need to "fix" the design flaws of devices they bought?

I'm not one of those people to "fix" the device, because when I found the polling speed and latency couldn't be increased, that was a complete stopper for me. I really wanted to make the mouse work for me, I really tried to make it work, but I couldn't get past the many flaws. It felt as if they went backwards from their old devices like the MX Revolution in many ways.

My MX Master 3 has a weird issue where it can just stop charging. Apparently this is just an issue it can have. The "fix" from Reddit is to squeeze the mouse until it starts charging again. It sounds like someone trolling, but it actually works about half the time.

I’m also going to return an MX Master 3S (to my employer though). I could only fix its weird scrolling behavior with Logitech’s bloatware, still, for the life of me I couldn’t improve the cursor precision on macOS, it’s was simply maddening to use it. Strangely on Linux the precision issue isn’t so bad.
