I found this shortcut which imports a markdown version of a webpage into obsidian vault and it worked beautifully. Now, however, it’s not working and I can’t figure out why. I didn’t change it at all! Here’s the shortcut:
Have you inserted your vault name in that first Text action? On the version you shared, there’s no vault name specified.
Otherwise, has your iPhone/iPad been updated? Sometimes OS updates include breaking changes for shortcuts, unfortunately, which then require manual investigation in order to fix whatever broke.
