Can't print read-only PDFs from iOS app

For about a month now, the iOS app doesn’t have a print option on PDF files shared to users as read-only. If they have full editing rights the print option is there, switch back to read-only and the print option goes away and is replaced by Delete file instead. Delete file doesn’t work, it does say access denied for that.

Using the web site instead the print option is there and works fine. We are on Nextcloud 25.0.5 and php 8.1. Any thoughts on what to try? Giving users full rights to files will create a huge mess.
