Phone authentication slow?

This is mostly a follow up on this post. Has anyone else had issues with phone authentication being slow? Specifically, auth().signInWithPhoneNumber taking a couple of seconds to complete.

I don't think this is inherent to Firebase, since I've used a couple of iOS apps (from the App Store) that use Firebase Auth, that don't have this same delay.

Has anyone had the issue and solved it? Or have any ideas what might be causing it?

I don't see any comments about it on firebase-ios-sdk, only the one issue here, so just throwing this out there.

Hi there - I get the impression not that many people use phone authentication, or they are very quiet. We don't hear about it very much at all, good or bad. I've used it and did not notice a multi-second delay but perhaps I wasn't paying enough attention. Given what appears to be near total silence on the feature set, if you want to get more details on where the time is going and where it will probably require personal investigation. That said, when doing ios auth with phone vs the emulators in our test e2e harness it is nearly instantaneous. So I don't know if it's the code paths in this module's code

Hey dqii,

Not much help, but just wanted to let you know I haven't encountered this issue at all on iOS.

It works pretty instant and flawless (Dutch number).
