Hello,
First off, I would like to say I really like the new UI and UX over the old app -- it's a great improvement. It also fits the macOS aesthetic much better in my opinion.
However, I'm using the app on an M1 MacBook Air for my MX Master 3 for Mac and pretty often, the app crashes. It is noticeable because the mouse stops working properly, e.g. scroll stops working, gestures using the thumb button, navigation via back/forward buttons etc. When i try to open the app it gets stuck on the loading screen and I have to restart to get it working properly again.
It might be related to waking up from sleep, particularly on the M1 processor, as I recall having similar issues with other apps if I left them open and put the computer to sleep before they got updated to run natively on Apple Silicon.
Thank you, and I hope you are able to find a solution to these problems soon. I am also looking forward to an Apple Silicon or Universal version of the app, because as I've said, the new version is a great improvement otherwise.
