Photo’s saying ‘Not Enough Available Space’ but there is...

Hi guys,

I have the latest model iPad 32GB. Settings > General > About tells me I have 20.86GB of available space.

I am attempting to import 6GB of photos from my SD card but I keep getting a pop-up stating

“Not Enough Space Available. Import requires 2.3GB more space”.

Why is this happening and how do I fix this as I clearly have enough space?

I tried selecting all the images individually, restarting....same issue!

I also note that I have 200GB of iCloud of which only 17.3GB is used. Photos are set to back up to the cloud and the ‘Optimize’ option is switched on. I

thanks in advance.
