I have a MacbookPro 2017 and I am only using the built-in trackpad. No extra drivers for Logitech or any other input devices.
When using the latest version of Firefox, it takes 2 or 3 tries to get the Gantt to scroll horizontally or vertically. And when it scrolls, it is very jerky and slow.
I have the exact same browser extensions installed for Firefox and Chrome, and there are no issues with scrolling the Gantt in Chrome.
I am using Firefox for 99% of my other work tasks, so it would be great to use Smartsheet there too. Instead of having to open Chrome for 1 task. Thanks.
