September 9th Release - Course Fixes and Additional Insights

Import from Medium, Substack, Twitter and YouTube
Four new places you can bring your own writing and content in from, joining LinkedIn, TikTok, Instagram and YouTube.
If a link can't be read, you now get told why rather than watching it fail quietly.
Voice capture is fixed
If you tried to create a voice capture on Sunday 7 September and it failed — that was us.
It's fixed, and the specific cause is resolved.
Courses
Your quiz answers stay put when you leave a lesson and come back.
Narration stops when you answer a question instead of talking over you.
Your AI knows what the quiz on screen is actually asking, not just which quiz it is, so asking for help gets you help about the right question.
A course opened from someone's profile now reads as a course rather than something else.
An older cover no longer reappears over one you just made, and a cover you asked for in chat attaches the same way a cover made with the button.
Lesson counts are right, quizzes with no questions no longer block finishing a course, and grading uses the answer key the creator actually wrote.
HEIC images work as course thumbnails.
Insights tells you when retrying won't help
If a document produced no insights, it will let you know.
There are two different reasons a document yields nothing: the extraction ran and missed, which is usually temporary and worth retrying; or the document was routed to be searchable text instead, which means retrying would make exactly the same decision.
The panel now tells you which one happened rather than offering you a button that couldn't have helped.
