I can't import from my SD card for my Panasonic on my iPad

I picked up a used Panasonic DC-GX880K and strangly when I plug in it's MicroSD card neither the the JPG files nor the raw files (.RW2) are showing up as valid imports in iPad Lightroom.  I can import them in cloud based MacOS Lightroom just fine (second screenshot) but in iPad "Add Photos -> From Camera Device" it just spins for ever presumably searching for photos, and in "Add Photos -> From Files" I can selet the files but when I click "open" it doesn't import them. 

What could possibly cause such an error?  

This replaces an old Olympus OM-D which broke, and using the same card.  However, I did format the card in the camera.  Could the format somehow be causing the problem?  

I am 99.5% sure that I could access the photos from the new camera when the new camera was adding files to the card before I reformatted it (when the card still had it's format from the old camera.)  I might have some cards formatted from the old camera (which just broke) so I could perhaps verify this with 100% accuracy.  

1. Version of the App: v 7.3.3 AC0CCD/29

2. Platform and OS Version: iPad Pro, iPad OS 15.5

3. Plug in an SD card formatted in a Panasonic DC-GX880K camera that has photos on it from that camera, click "add photos" -> "from camera devices"

4. Expected result: shows some photos to import.  Actual result: progress wheel spins forever, no photos show.

5. Notes: files show in Files app on the iPad, and can be imported on the MacOS version of Lightroom.
