I did not find another place to report this bug so hopefully this is not too out of place.
There is a huge bug that currently prevents my clients from using Timestamp fields. If a Timestamp field is saved using the legacy editor, it queries fine. But when the Timestamp field is saved using the "new editor experience", it returns null.
I love Prismic but updates like this really hurt the trustworthiness of Prismic. At least give the option to permanently disable the new experience for all documents instead of having to do it manually every time opening one.
Can someone confirm they experience the same issue? I'm using Nextjs.
This is a known bug in the Page Builder Alpha. The team has plans to fix it this week.
In the meantime, I have moved your repository back to the legacy builder.
