Okay. The file system based hosting of your notes is key. The utilisation of Drafts is perhaps personal preference, but given you are willing to go a bit more manual than fully automated certainly makes a big difference in how workable this is.
You note the action you are using isn’t working. I’m on the beta, so if you share the details for the action, I can take a look; but I’m not currently aware of anything in the beta that would affect an action iterating through the tags and writing them back as hash tags into the draft or an export.
