I'm testing Fedora Silverblue 39 currently, and the Dropbox experience is not great.
I installed the latest version of Dropbox from Flathub, launched it and signed in without issues.
But as soon as I closed the settings, I couldn't reopen anything. Relaunching the app just open the folder in Files.
I tried installing the AppIndicator and KStatusNotifierItem Gnome shell extension, but after launching Dropbox it crashed with an error `Util.DBusProxy is undefined`
Looking forward to being able to use dropbox on the latest Silverblue!
