I want to customize the landing page of my portal with python. I have found a set of examples here: https://developers.arcgis.com/python/guide/customizing-the-look-and-feel-of-your-gis/. But it seems that some of the functions do not work with Portal 10.9 and the new homepage editor (expl. setting background image). Additionaly i don't find any solution to cutomize shared theme settings (logo and theme colors) and organisation defaults.
Has anybody solutions for theses things?
