Embedded webviews are the stupidest thing ever. Yesterday I got halfway through a checkout process, had to go back to another app to check something, and then the webview simply disappeared so I didn't bother finishing the checkout. This was on Android
Usually I open it in Chrome but for some reason I didn't realize it was a webview this time
I disable them on every app that lets me. It is in every way worse UX than simply opening the browser.
Embedded WebViews are a way to track you:
