Hello! I am the upstream maintainer of Burgernotes (formally pageburger) and we would like to change the ID of burgernotes to match to new name. We would also appreciate it if the old ID was used as a redirect to the new application.
Change ID of org.hectabit.PageBurger
Then you want to publish a new flatpak with the new id.
If that’s available you should be able to follow the docs here Maintenance | Flathub Documentation
