I have a feeling that the thing behind Summarize that pulls the actual text to be embedded isn't getting the full page when it encounters a Discourse forum post.
for example this page: https://community.openchargemap.org/t/integration-with-openstreetmap/110/31
- Summarizer claims I only saved 1 minute of reading
- It doesn't seem to have gotten the full context of the convo
I assume what's going on here is that you're running into the problem of Discourse where it 'recycles' div's instead of making new ones.
So it only loads the first couple of messages in a post and as you scroll down, it replace the top div's with new content and puts them at the bottom. (a technqiue web devs use for perforamnce). But you'd have to somehow load every single message in a thread
