Wolfgang, I noticed this issue in the context of codim 1 cells. Newton method has a great convergence rate BUT it requires the initial guess to be close enough to the root. This seemed to be one of the issues in the case I'm referring to.
To make it work I needed to find a better initial guess than the default (0.5,0.5). One working so far implementation of this idea is in the branch_codim_two branch. Unfortunately it needs some documentation and cleaning. It's in my TODO list but spare time is not on my side at the moment.
