Why is Continuity for Markup not working?
I'm trying to annotate a file on my iPad Air 4 using my Apple Pencil while reading from the same file on my 2018 MacBook Pro 13". Clearly, using Continuity Markup, as described in this page (https://support.apple.com/en-us/HT204975), is the solution for me. However, when I get to Step 2 of the directions for Continuity Markup, I simply do not have that annotate button. Instead, I have this:
When I click on this button, my iPad tries to open a Preview window to annotate the document but the document never loads and the application quits to the home screen. Why is Continuity not working?
