There appears to be an issue, recently last 1-2 months Dec 2022 Pika Backup, Deja Dup Backup and other Flatpak installed apps from the pureos store cannot store or unlock the encryption password created for the backup archive.
Pika Backup just generates generic error user interaction failed
Deja Dup pops up a window asking for encryption password entry (even though remember me was selected previously)
The Deja Dup Debian .deb installation correctly stores and retrieves the password from the Gnome Keyring.
Is anybody aware of these type issues? Is that a Flatpak issue or PureOS issue?
By the way fixed again with a recent update to the Gnome 43 Application Platform yeiks.
