I installed this application with flatpak. If a theme is installed with flatpak and that theme is downloaded and applied via dconf, this application currently does not apply the currently used theme. Other applications change theme, but this one sticks with the old-ish Adwaita look. A current workaround is to change flatpak filesystem permissions to allow xdg-data/themes and then use GTK_THEME debug variable to forcefully apply a theme.
