Not parent, but the web player used to be a down-graded experience from the native app. If you need Zoom for a professional setting, those functions could be important.

Do not know if this is still true, but at one point, the web player would only let you see one speaker at a time, while the app would show multiple people at once.

99% of the time I use the browser.

However, the video quality in the browser is worse, so depending on the use case I might have to use the app (via sandbox).

It's been years since I've had to though.
