I’ve been trying to capture formatted text from Arc Browser using Apple Shortcuts, Keyboard Maestro, etc. and haven’t had any luck so far. It’s odd because I can manually copy and paste the data from Arc and it keep the formatting in Obsidian, but using Apple Shortcuts doesn’t work. I’ve tried using the “Shortcut Input” route which works flawlessly on iOS and I’ve tried the “Copy to clipboard” and “Get clipboard” actions to try it that way, but still nothing. It loses all of its formattings and doesn’t keep bullet points or anything.
I don’t have experience with Obsidian, but the problem might be that Obsidian is grabbing the plaintext representation of the text and putting that in. Have you tried putting in a Markdown from Rich Text action?
