i somehow lose (track of) the ability to create and augment collections depending on how i authenticate.
if i use google, i the collection page displays a full list of collections and have a button to create a new one.
if i use github, on that page, only the “new” notebook button is present at the top and neither a notebook page nor the notebook listing indicates any means to add a notebook to a collection in the “…” pop-up menu.
is there something about different login references which matters?
