Hello Niels
I might be the outlier here as I try to get it to work with Sidecar in macOS Catalina 10.15.4 and iPad Pro 12,9″ 3rd generation running iPadOS 13.4.1
With the recent update, I manage to get a little pen pressure, but then I need to press quite hard. Since I do my daily work as an editorial cartoonist and illustrator with this setup, it would be convenient if it would work with Animation Paper as well, but I can understand it if you would concentrate on like Wacom tablets first, but thought I’d mention it at least.
