/conv/ - Conversion Rate

we noticed a significant drop in completion rates specifically on mobile devices during the final step of our funnel. desktop performance remains stable, but the mobile flow feels clunky when users try to enter credit card details. we tried simplifying the form fields and removing unnecessary inputs, but it hasnt changed much.
>the bounce rate is spiking right at the shipping method selection
is anyone else seeing this w/ certain one-tap payment integrations ? i am wondering if we should test a complete redesign of the mobile keyboard layout or just stick to standard form optimizations for now. any advice on tracking if it is a technical bug or a usability issue would be great.
