How to fix a connection that has an error
There are several types of errors that can occur with your connections.
Account Errors - Authentication tokens are used to securely access your data which constantly expire and therefore need to be refreshed periodically. The authentication can b revoked or have an error refreshing, which break the connection. If this occurs you will be sent an email informing you that you will need to connect again. Please follow the Google Account error steps below to re-establish the connection.
Service Errors - Permissions and settings on your Accounts can change over time and can cause errors in connecting to the Service. For example if you setup a Client that uses a particular Google Analytics Property (View) and that gets changes deleted in favour of another one. Any connected features will break and require you to remove anything connected to it and then reconnect.
To fix a Service error you will need to Delete or Archive any Active Jobs (KPIs, Budget, Automations, Anomalies) and then update the settings.
Note: Currently it is not possible to edit the Service settings (Google Analytics View, Google Ads Account, GMB Listing or Search Console property/domain) if it is being actively used. This is to ensure that any active jobs continue to work as expected. For example if you set up a KPI that uses a Goal, changing the Analytics view can break the KPI as the Goal may not exist or be a different Goal than intended.
Google Account Error
To fix a Google Account connection which has an error, click on the 3 dot menu (also called overflow menu) and then click Reconnect. You will need to complete the Auth process again and sometimes a refresh of the page is required as all linked KPIs or Budgets will be updated.
