New photos not adding new locations on map

Nextcloud version 18.0.5.1
Ubuntu 18.04.4 LTS (lxc)
Apache 2.4.29
PHP version 7.2.24

Hi comunnity,

since april the locations to my uploaded photos won’t show up in the map anymore.
I checked whether the latest uploads contain location data: they do.

Your help would be greatly appreciated.
