Unable to login with Facebook using Snap

[ltrager]

I'm trying the new Spotify Snap on Ubuntu 18.04 but I am unable to login using Facebook. When I click the login with Facebook button I get the following dbus error.

$ spotify
Gtk-Message: Failed to load module "canberra-gtk-module"
Error org.freedesktop.DBus.Error.AccessDenied: An AppArmor policy prevents this sender from sending this message to this recipient; type="method_call", sender=":1.93" (uid=1000 pid=14375 comm="dbus-send --print-reply --session --dest=io.snapcr" label="snap.spotify.spotify (enforce)") interface="io.snapcraft.Launcher" member="OpenURL" error name="(unset)" requested_reply="0" destination="io.snapcraft.Launcher" (bus)
