Problems importing photos from SD card to IOS 15

I am trying to import photos from an SD card into my iPad on IOS 15. When I plug my adapter in, nothing happens. I can plug the same adapter into a different older iPad (older - IOS 12) and the adapter and SD card work. I have tried 2 adapters, 2 different SD cards and even rebooted the iPad in question. Something seems to have changed where I cannot import SD cards using an adapter anymore into my IOS 15 iPad. Anyone else seeing this?
