Hi @Gnopps, fellow user here.

This isn’t a bug; it’s a breaking change introduced in v1.9.0:

We have officially removed support for the properties tag, alias, cssclass in favor of tags, aliases and cssclasses. In addition, the values of these properties must be a list. If the current value is a text property, it will no longer be recognized by Obsidian.

So in your specific case, the tag property is no longer supported by Obsidian. As you noticed, Obsidian now only recognizes the tags property, and the value of the property must be a list.

Hope this helps,

Craig

Ah, I see. Thank you for highlighting it! Then I guess I need to find a way to convert all my notes automatically…
