A/B Testing troubleshooting and FAQ

How many experiments can I create and run?

You are allowed up to 300 experiments per project, which could consist of up to 24 running experiments, with the rest as draft or completed.

Why can't I view my experiments after unlinking and relinking my project to Google Analytics?

Linking to a different Google Analytics property will cause you to lose access to experiments created beforehand. To regain access to a previous experiment, re-link your project to the Google Analytics property that was linked when the experiment was created.

Why do I receive a "Project not linked to Google Analytics" message when creating a Remote Config experiment?

If you've already linked Firebase and Google Analytics, but still see a message that Google Analytics is not linked, make sure that an Analytics stream exists for all apps in your project. Currently, all apps in a project must be connected to a Google Analytics stream to use A/B Testing.

You can find the list of all active streams on the Google Analytics integration details page within the Firebase console, accessed from settingsProject Settings chevron_right Integrations chevron_right Google Analytics chevron_right Manage.

Creating a Google Analytics stream for any app that does not have one should resolve the issue. There are a few ways to create streams for missing apps:

• If you only have one or two apps missing an associated Google Analytics stream, you can choose one of the following methods to add a Google Analytics stream:
  • Delete and re-add any app without an active stream in the Firebase console.
  • From the Google Analytics console, select Admin, click Data Streams, then click Add stream, add the missing app's details, and click Register app.
• If you have more than a few missing app streams, unlinking and relinking your Google Analytics property is the fastest and most efficient way to create the missing app streams:
  1. From settings Project Settings, select Integrations.
  2. Within the Google Analytics card, click Manage to access Firebase and Google Analytics settings.
  3. Make a note of the Google Analytics Property ID and the Linked Google Analytics account.
  4. Click more_vert More and select Unlink Analytics from this project.
  5. Review the warning that appears (don't worry here; you will relink the same property in the next step), then click Unlink Google Analytics.
     
     When unlinking is complete, you'll be redirected to the Integrations page.
  6. Within the Google Analytics card, click Enable to begin the relinking process.
  7. Select your Analytics account from the Select account list.
  8. Next to Automatically create a new property in this account, click edit Edit and, from the Analytics property list that appears, select your property ID.
     
     A list of all apps in your project appears. Existing stream mappings for each app are listed, and apps that do not have a stream will have one created for them.
  9. Click Enable Google Analytics to relink the property.
  10. Click Finish.

If you still receive an error creating A/B Tests with Remote Config after performing these steps, contact Firebase Support.
