I've tried many different methods in order to activate the collaborative mode on Jupyter Lab and I didn't expect it to be a particularly difficult task. Apparentely, all I need is to update the jupyter notebook server to the latest version (2.0 or more) but nothing seems to work.
From the Anaconda Prompt, I attempted to update conda, the anaconda navigator, jupyter notebbok, the jupyter server... it keeps saying that "all packages are already installed/updated" but the server version remains the same. Is there a simple way I can make this work? :(
