My main gripe with this is the pretty shocking performance on old "supported" iOS devices (e.g. an iPhone SE 2). When you have too many tabs, or watch more than a couple videos it just starts freezing and will sometimes crash the phone - you get an unresponsive sideshow screen for a bit before it goes to the lock screen with fingerprint login disabled (like after a restart). I can only assume they've accidentally found a way to make webkit leak memory?
