Our engineers are working on a fix which will revert connectors using legacy (OAuth) authentication to using Apple Ads’s API version 3, rather version 4. However, we highly recommend to our customers that they change their authentication method to OAuth2 to benefit from using Apple Ads's API version 4, which provides the most reliable data. We expect the fix to current issue to be deployed later today.

All the connectors using the legacy auth are currently failing. We are continuing to investigate the issue.
