With the latest snap versions of firefox and thunderbird on ubuntu 20.04 I’m having issues using ‘save link/image as’ functions. The thunderbird 91.3.0 version in the latest/candidate channel also fails to save single attachments (saving of all attachments together seems to work sometimes though). It looks like the calls to xdg-document-portal are failing with the following error:
Invalid id snap.thunderbird: Names must contain at least 2 periods
Invalid id snap.firefox: Names must contain at least 2 periods
Has anyone experienced the same issues?
