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

Hi @marcusx2,

Certain environments like Safari iFrames restrict the usage of browser APIs (like IndexedDB) that the Analytics SDK may require. This is a Safari feature called Intelligent Tracking Protection and it prohibits Analytics usage in that environment.

In general, you can programmatically check if the environment supports Analytics by invoking isSupported. If the promise returns false then the browser enviornment lacks the features that Google Analytics requires.

I hope this helps.

So there is no workaround?

It returns true...

Thanks for letting us know. It looks like the Stack Overflow issue you linked to shows that Google Analytics in general doesn't work in Safari iframes, and not Firebase Analytics specifically. So it's not a indexedDB issue or other issue in the Firebase SDK.

If you can't find a workaround and need further support, I would suggest contacting Google Analytics support. If they (or the community) have a workaround for this and you're not sure how to apply that workaround in the Firebase SDK, let us know and we can help with that. Otherwise there's not much we can do in this SDK.

Let us know if that's incorrect or there's any other information you have indicating a fix can be done in the Firebase SDK.
