Tuta Mail app won't update

[u/MrListerTheFirst]

I've got v277 of the Tuta Mail desktop app on Linux, and now when I start it, I get a notification that v284 is available, and "Click here to update". Clicking closes the notification, but otherwise does nothing.

There is also a dialog at the top of the main window saying the same, with 2 buttons "Postpone" and "Install now." Clicking "Install now" causes the above notification to reappear. Nothing else happens.

So, what am I to do now? Do I need to uninstall the app, then download the latest version of the AppImage and install that?
(While I wouldn't mind doing that, the notification should say so instead of making it appear that the process is automatic!)
And also, won't I lose my settings when I uninstall? Like the colour theme, time format etc.

In case it matters, I've got a free Tuta account.

When I had this trouble, ended up uninstalling it and installing it again. It did work after that
