I think this was happening because Safari was auto-denying the site's location requests, due to https://openradar.appspot.com/FB7716779. We can improve the instructions to explain how to give Safari permission to give websites permission to get location, at https://github.com/jyasskin/sidewalk-obstruction-bingo/blob/main/components/get-location.tsx#L67, using code like https://github.com/jyasskin/sidewalk-obstruction-bingo/blob/main/components/instructions-accordion.tsx#L29 to only show details to iOS folks.

@clvlach, can you write the wording for that?
