content: worth the effort to learn if you need a crossplatform multibook note taking system that syncs well. I had to uninstall the default office app on me new W11 laptop and reinstall the app on my phone. Also found it best to use a dedicated folder for my notebooks. Now I use it constantly to make quick notes on my phone and large scale changes. It is really good to keep several different types of journals and project ideas and now suncing is very smooth. Just need to make sure its up to date.
