I love web-based IDEs but I haven’t found one that works with an iPad yet. AWS Cloud 9 kind of worked up until iOS 13 but now it complains about third party cookies and refuses to let me in. Before iOS 13 it worked but the keyboard had a lot of problems.
Should be possible, but in my experience it’s just not right now.
Hopefully its implementation is browser and OS agnostic on the client. I've had difficulty using Office 365 and OneDrive web access on Linux, which means I can't even consider using those services in a professional workflow.
