Description

Recently when testing our app for iPad Air (5th generation) on iOS 18.4 or iOS 18.3.2+ an issue connecting to Cloud Firestore has caused our app to not pass Apple's review stage.

I should mention, the simulator is indeed connected to Internet as I've double check many times with Safari when testing.

Initially I thought it was the Firestore configuration, it's odd for me because if I freshly install the app on the simulator device it works fine, yet say I close the app after a fresh install, or just use it normally then this error arises and causes Firestore to not connect.

For context the following is a reference to the issue at firebase-js-sdk and a reproduction repo for testing:

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

This looks like a Firestore variation of #14677. cc: @ncooke3

This may not be the right repository for this issue. Where is the NSURLSession usage coming from? Capacitor? Wherever it is may need a similar workaround as discussed in #14677.

@paulb777 You may be right, it seems I've been able to come up with a workaround in @ionic-team/capacitor which atleast allows Firestore to connect.

Sounds good. I'll close for now, but feel free to reopen if you find something else.
