Limited Import from SD card to LR mobile w IPAD OS.

I am trying to import photos from my SD card, via the files app. Using IPad OS on IPad Pro.

From the files app I select the images, and click share.

I can import a few images only this way. Max 8.

When I try to import the whole camera roll, the LR option disappears from the share menu.

Is there any other way to import a whole SD card folder of images into LR without using the photos app?
