There needs to be a way to force a build in Pages.
Currently, the only trigger to a new build is when the repo branch has changed.
If you change a setting, no build starts. You must make a spurious change to your repo and push it to trigger the build.
MUST HAVE MANUAL BUILD.
I think you are worried about too many people building too often. Really: that won’t happen. We don’t build because we want to. We build because we need to.
There are other UI changes and features that are needed, but this is critical.
