It depends where you've saved them. Most likely place is iCloud Drive. Run Pages and when it offers to create a new document, click on the + sign in the top left corner NOT the one in the blank Create New document. You should then see iCloud Drive, tap that and select the Pages folder.
Thanks Mick - I've done that and zilch!!
I'm wondering if as I'm away the weekend I need to connect to my iMac when back home as I am hoping they are somewhere in the iCloud ether.
I know there have been lots of complaints that Apple need to sort this one out.
Many thanks again
