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.
