A friend has created a Google Maps list so that we can both starting adding to it places of interest for our upcoming holiday. He set that list to "shared", i.e. there's now a private link to it, which I have. Indeed, when logged in with my own Google account, I can see that list and its contents, and "follow" the list.
However, I cannot add anything to it. That is, when I navigate to a place in Google Maps and click Save, all I see are my own lists, and not also the said shared list which I'm following. I'd additionally like to be able to delete existing saved places from the list.
I'm guessing this feature is simply not yet available, otherwise Google would have made it easy to use.
What I wonder, though, is whether any workaround can be thought up to achieve my aims?
