Our company's web-based product relies on the pointerEvents API, and specifically the stylus pressure input. It seems in the last year, support has changed for this option... and is very difficult to track down a solution. It has been suggested that the Windows 10 "Fall Creators Update" has caused these issues, but little information exists. It has also been suggested to use Firefox ESR to gain the functionality back, but so far my stylus' pointerType is detected as "mouse". I'm using this utility to test input data from my stylus and other pointer inputs. https://evitolins.github.io/pointer-events-debugger/#pointerdown,pointerup,pointermove
