Apologies if it has been covered elsewhere, but is it intentional that the site breaks (will not show any pins, whether going to the overall map, a post link, or a user link) if location permissions are not given. I tested this on both Safari (not locked down in any way) and Brave (both locked down to prevent 3rd party everything, and then also with very little blocked), both on Mac OS 10.15.6, so if this is unintentional then it seems like a pretty major bug.
I am currently on my way to Berlin but will try to take a look at it the upcoming days. It might be that the script breaks somewhere when not having location permissions (it's only used to show where you are on the map, so it should definitely not be a necessity for the map to work)! Thanks for pointing it out! 😄
EDIT: I tried to recreate this issue and was unable to in Brave nor in Chrome, will try Safari later. I might need some more details on how you blocked location services.
