Thanks all for the feedback. We understand it’s not expected to change this behavior. From our perspective it was a bug we long wanted to fix, as most people expected the current/new behavior. The reason we did it before Matomo 4.0.0 release is because it can greatly improve archiving performance in some cases. It was mentioned in the changelog quickly, here is the original issue: https://github.com/matomo-org/matomo/issues/11900
