True. But unless people use the latest (I love testing beta/canary/pre-production of anything) it is hard to move things forward.
Working on Vercel is different to working on Netlify. They are different platforms, different methodologies, etc. Next.js is developed/maintained by Vercel, so they will always have the upperhand when it comes to supporting the latest builds/features. (This is purely my opinion. I neither speak for Netlify or Vercel.)
Have you checked you are using the latest plugin version as @ascorbic mentioned in the your previous thread?
Am sure Support/Software Engineering teams are much better placed than I to provide support here.
