Why iPad widgets are less flexible than iPhone widgets?
With iOS 14 on the iPhone, you can have widgets anywhere you like, on any screen. You can mix-and-match apps and widgets as you like.
However, with iPadOS, widgets are still limited to the sidebar – and only on the first screen. You can’t freely mix-and-match apps and widgets across the full width of the home screen, and you can’t have widgets on the second or subsequent screens.
Why would you make a more powerful device with a larger screen less capable?
