Per the docs, this should be being synched on first analysis of the branch. Are the FPs marked in your main branch? And if so, can you share the analysis log from the first analysis of a new branch?
Okay, so you’re introducing an issue in a (non-main) branch and the pain point is that on its journey to main, it keeps showing up in intermediate branches.
So yes, once the issue makes its way to main and is marked FP there, that will be propagated to all subsequently-created branches.
In addition, there’s something in the docs about using a reference branch for the New Code definition, although I’ll be honest and say the meaning isn’t clear to me. So FWIW. (And yes, I’ll be raising this point internally.)
