I’ve tried it from the three dots, from CMD-P, from the side panel, and in edit mode using —. none work. I can tell that when I type the — the first visible line number changes from 1 to 4, but that’s the only evidence of anything happening. I know that before, when I selected properties in the side panel I had a + New property button, but not now.
As a workaround I can create a new note, insert a template (that had properties) and then delete all the template stuff and put what I need in the note.
I don’t use the Sandbox, as I’m not a developer type, though I’m becoming more of one to keep tweaking Obsidian. Yes, I did find that if I go into the Editor settings and change “Properties in Document” to visible, I can now add a property. As soon as I do that, then all the other ways of dealing with properties become available (CMC-;, more options, side panel, CMD-P) are all functional.
Seems the issue is known and will be fixed shortly, but for the record: the Sandbox isn’t for developing or anything. It’s just a vault that resets to play around in with the default settings, no community theme, no CSS snippets, and no community plugins.
It has the added bonus of being an easy way to see if an issue you have in your own vault also exists there or not.
Thanks. Yes, I’m famiilar with sandbox, but its more a matter of time that I don’t have the luxury of trying things out. Running my business takes most of my time. I’d love to try more things. I’m still wrapping my head around Dataview.
