DropBox access
Since updating the iPad Pro and iPhone X to the latest version 14.4, I am no longer able to view the DropBox folders from the Files app; I get the message 'Content not available. The contents of the folder could not be shown due to an unknown error '. It works fine on the MAC with Big Sur 11.2.1 and the DropBox app works regularly as well.
iPhone X, iOS 14
