Bug with Mapbox or Glide?

My app’s URL:
Hi all -
Im hoping someone can please weigh in the current issue with Glide and User Location?!?
It’s hard to ascertain if issue is with Glide or Mapbox? Either way, user location (as a function) is not working.
User location is lost upon pinching / zooming in on map.
Users location cannot be geolocated or sourced whilst using maps.
Many thanks
