@abettermap I don't believe there are any other instances where the user is waiting while firebase authenticates. Were you thinking of anything specific?

[abettermap]

Oh I meant just waiting for requests to complete in general, not just firebase (e.g. "forgot passwd"). If you think of any please add an issue!

[ajsamra]
