Detailed Problem Description

These screenshots are logs from Bugsnag. As you can see, any iOS gives us this warning. Does firebase-js-sdk work on iOS?

Also, the app is using https and there is a SSL certificate (I am noting this since I read some threads discussing this, so we can exclude that).

Steps and code to reproduce issue

Access the app with iOS device.

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

Hi @mislavmiocevic, FCM is supported on modern mobile browsers.

This error messaging/unsupported-browser is thrown if any of the required APIs are unavailable in the users' browser. These APIs include:

• IndexedDB
• Service Workers
• Push Manager
• Notifications
• Cookies
• Fetch
• DOM

A users' device may have a modern browser without one of these APIs enabled for various reasons. For example, if they have security or privacy settings that block cookies or IndexedDB, FCM will not be able to work.

If all of these APIs are available, and this error is still thrown, it is definitely a bug.

Hey @mislavmiocevic. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

I think with iOS, Web Push notifications are only available for PWA (home screen apps).
