Please describe the issue here:

The new Firebase Crashlytics fails to work both on iOS and Android when build from banchmode.
This can be checked by installing the quickstart crashlytics sample project with the new UPM package version.
I get this error during build:

Crashlytics could not send build event. Error: HTTP_REDIRECT_ERROR

On android I was able to find that Firebase.Crashlytics.Editor.VersionInfo:GetEditorGvhVersio is hardcoded to search for configs in Assets/Firebase/Editor because of the following error during build time

On iOS I was able to fix it by following the this resolution and add the link.xml file to the project

<linker>

    <assembly fullname="Firebase.Crashlytics" ignoreIfMissing="1">
        <namespace fullname="Firebase.Crashlytics" preserve="all"/>
    </assembly>

    <assembly fullname="Firebase.App" ignoreIfMissing="1">
        <namespace fullname="Firebase.App" preserve="all"/>
    </assembly>

</linker>

Please answer the following, if applicable:

Have you been able to reproduce this issue with just the Firebase Unity quickstarts (this GitHub project)? Yes

What's the issue repro rate? (eg 100%, 1/5 etc) 100%

Hi @CoderGamester

I think this is the same issue with #623

Please use .unitypackage version of Firebase SDK if you are using Crashlytics at the moment.

Duplicate of #623

Hey @CoderGamester. 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!

[CoderGamester]

not fixed yet

[mrichards]

Firebase engineer here. The Folder not found error will be fixed in the next Firebase Unity release. We could not reproduce #623 so we're not certain if the same fix resolves that issue.

[chkuang-g]

Should be fixed in 6.15.2.
