iOS 14.3 beta 3 bugs:
Intermittent scrolling in the App Library
The list of recently closed tabs in Safari opens for a Long time
When viewing a video in Safari, if you quickly tap the screen 2 times and then tap again, the video is either too large or too small, and you can't return it to its original state
When using the password AutoFill function in Safari, the password menu takes a very long time to open
After entering your username and password and clicking log in on any site, Safari freezes for 15 seconds, then continues to work
