Perfectly working on Mint 20.1. It good if you are looking for the latest version.
Using the install version 3.47.1 with no problems on Linux Mint 19.3 Cinnamon 64b / TY to the FlatPak system.
The interface is nice but there's no change in the cursor when dragging files across and it refuses to pick up text editors when set. So I'm removing this version and reinstalling the original one as it's functionality is limited at the moment.
Can't edit file with code editor! Even with --filesystem=host flatpak run --filesystem=host org.filezillaproject.Filezilla When connected to server -> RMB on file -> View/Edit For editor i'm choose /opt/sublime_text/sublime_text OS Linux Mint 19 (Ubuntu 18).
works like a charm, thanks!
