Failure to load Google Drive images as backgrounds on new Huawei P20

Hi all, I got a new phone running Android 10 and reloaded KLWP Pro and brought some of my pre-sets in for changing. But whenever I access a .jpg photo on Google Drive, all I get is a 'Loading' message - no matter how long I leave it. Pretty sure KLWP is working as it did, so I'm wondering if it's a permission problem with drive.

I also don't see any mini icons next to the photos - just the same icon, which makes it difficult to make a choice on which photo to use.

Can anyone shed any light on this for me please?
