LR Mobile does not import geotagging info if they are from an other source then the iPhone camera

I was hoping that iOS 13 would solve/improve the issue. With the Public BETA 3 More is working now but it fails in the end.

The goal is to geotag RAW photos from a LUMIX before importing them into LightRoom Mobile

1. In iOS Photos I create a folder on the iPad named “from SD card”
2. I import the RAW pictures from the camera using the Apple sd card reader into the folder “from SD card”
3. I use Geotag Photos PRO to geotag the photos in the folder  “from SD card”
4. I check in iOS photos and they are indeed geotagged  
5. I import into Light Room MOBILE and the geotags are missing ☹
6. When I import pictures taken with the iPhone camera and then to an import into LR mobile the geotags are there

This means LR mobile rejects/ignores geoatting information wihch is sufficient from iOS Photots

Can anybdoy think about a work around ?

Many thanks in advance.

regards
