The Analytics Edge connectors ‘GA Management’ and ‘Google Analytics Pro’ have features that use the Google Analytics Management API in order to change filter settings.
Google identified (and fixed) a problem with management.filters.patch and management.filters.update operations that may have caused filters to become unlinked from the view. This problem was introduced on 5/23/2017 and fixed on 6/19/2017. Please take a moment to see if your account has been affected by inspecting the views and checking that filters are properly linked.
Linking the filter back to the view should address the problem. If you need help recovering from this problem, send an email to [email protected]
