Are V2 of GCP APIs generally worst than V1?

Of the GCP APIs I've integrated with, I've noticed the later versions are worst than the v1. I am not talking about beta and alpha versions, but supposedly generally available V2.

For instance, I used Google Cloud Functions V1 and V2 API. The V2 API returns no results when listing functions, whereas the V1 API correctly returns results.

Can't discern if this reflects a downward trend in GCP's product quality, or just the nature of GCP's API product life cycle.
