General troubleshooting/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 settings Project 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:
- From settings Project Settings, select Integrations .
- Within the Google Analyticscard, click Manageto access Firebase and Google Analytics settings.
- Make a note of the Google Analytics Property IDand the Linked Google Analytics account.
- Click more_vert Moreand select Unlink Analytics from this project.
- 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 Integrationspage. - Within the Google Analyticscard, click Enableto begin the relinking process.
- Select your Analytics account from the Select accountlist.
- Next to Automatically create a new property in this account, click edit
Editand, from the Analytics propertylist 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. - Click Enable Google Analyticsto relink the property.
- Click Finish.
If you still receive an error creating A/B Tests with Remote Config after performing these steps, contact Firebase Support .
