This is a big barrier if you want cross-compatibility and making Linux usable for everyday people. My whole interface is a terminal and a browser. I could use/pay for something like this in the same way I use figma. I don't need an app and when I open my iPad I can access whatever I was working on.
The browser should have been the place to run all of this from the very start; but Apple/Google decided to create walled gardens for their systems.
