For what it’s worth:
- If I select the link inside the Discourse app on my phone or iPad, it triggers Scriptable.
- If I enter it into Safari on those devices it gives me a GitLab 404 page.
- If I open the URL via Shortcuts on those devices, it triggers Scriptable.
- If I open it from a link on the page in Drafts, it gives me the 404 page when opening internally, but if I choose to open the link in Safari rather than Drafts’ own internal web view, then it triggers Scriptable.
My devices have been rebooted, but my point is that the result varies a little based on where and how I am triggering the URL.
Maybe that somehow plays into the issue?
