iPadOS 18.6.2 (iPad) error when creating iPages files on pCloud

I get the following error on ios 18.6.2 (iPad) when trying to create ipages files on pcloud:

“The requested operation couldn’t be completed because the feature is not supported. The requested operation is not supported” or

“The file couldn’t be opened because you don’t have permission to view it”.

ipages works ok for Dropbox, box etc but not pCloud.

How do I overcome this problem.
