Welcome screen was a popover on iPhone (only available on iPads, should be a sheet on iPhone), with rounded non standard button and non standard horizontal lines.
“Signed in as” toast wasn’t designed for iOS rounded bottom and “swipe up” bar leaving ugly stripe.
Sheet easing is off, and FPS stutter.
No swipe from left to go back support.
Non standard animations all over. Visible FPS issues (on newest HW)
I could go on and on. Feels like an android app running in an emulator.
You asked how it doesn’t feel native. Using a design system from a different platform, and not complying with the interface guidelines of the current platform, is a big part of not feeling native.
And the frame drops and lack of system gestures, and lack of standard nav stack are major infractions on usability outside of design.
