I have moved from 18.04 to 20.04 using a clean OS install and then re-installation of all used packages. One of the tricks I've used in the past is to create Web applications in Gnome Web (Epiphany) for frequently used sites. These would appear under 'Show Applications' and could be added to favourites in the dock and integrate with notifications etc.
This has stopped working in 20.04, I guess because the default Epiphany install is via Snap - the web 'applications' I re-created are now not shown at all under applications and can't be run in the same way. I can confirm that if I go to about:applications in Epiphany they are listed and are also in my profile under ~/snap/epiphany/current/.local/share/applications as .desktop files.
My installed versions Ubuntu 20.01.1 LTS Gnome 3.36.3 Epiphany 3.34.4-1-g606db9aec
A workaround to re-create the past functionality would be much appreciated.
