I listen to Radio 4 quite a bit and occasionally want to check the schedule (https://www.bbc.co.uk/sounds/schedules/bbc_radio_fourfm)
On mobile, Googling 'radio 4 schedule' is the quickest way, and the only negative bit about the entire experience is the popup that tells me 'it's better in the app'.
It's not. Not by any metric.
My search and opening a webpage takes a second or two. Opening the app takes several seconds, then navigating to the Radio 4 page and scrolling down the schedule takes several more.
I submitted a bug report on the topic and they basically told me "we hear you but shush and use the app".
