I've been using my personal space to test out some features before trying them in other shared spaces, and I have noticed that things get a bit... weird... when editing in a personal space. The first thing I noticed was that the Placeholder Text macro is not available in my personal space. I can copy something with the macro INTO my space, but cannot use it in the editor (and it is not in the + menu either, I checked).
I also just ran into an issue where I am unable to create a page from the Create Page From Template button macro.
My assumption is that the template Atlassian uses for personal spaces was created in the old editor, and doesn't get updated when published for the first time. I am just guessing here though...
Anyone else have these kinds of issues?
