My iPad is telling me there is insufficient space for me to download a movie but I just bought more data so I know there is enough! Any ideas as to why it is doing this?
You cannot buy more memory for your ipad at all.
I am guessing that you purchased icloud storage, which has nothing at all to do with the storage capacity of your ipad.
You need to delete some content from the ipad to make more room.
