Keynote demands update to V10 for collaboration
We are working with Keynote 9.2 and, during the Coronavirus lockdown, we have been using its collaboration feature. Now, when I try to use it, it advises updating to v10 and collaboration no longer works.
V.10 apparently requires OS Catalina, but we can't update to Catalina just yet because a lot of our other software tools are not yet updated to Catalina. When I press the Collaborate button, it offers just three options: Go to iCloud.com, Not Now and Go To AppStore. Can anyone help get us working collaboratively again?
Thanks
