Geo location invisible in Lightroom mobile

Hi,

my photos are geo tagged using the LR Classic map tool. I use the synchronisation of some albums to make the photos available in LR mobile on iOS. The problem I just discovered is, that all those gps coordinates don't exist in the LR mobile app. When exporting the pictures to my photo roll on ios the gps information is missing.

Viewing the images in the desktop version of LR (not classic) the gps location is shown. 

Is this a known issue?

Best,

Frank
