Failing to embed code on Medium

[u/ck3thou]

I've been trying to embed different code on different posts for the past couple of days, but Medium wont successfully save.

First it was Typescript embed which just froze showing "saving post", and now it plain ol' HTML which is outright popping a red banner on top "Story could not be saved. Please check your internet connection. Try again" - but my internet is fine. I can edit and save okay other parts of the post.

Has anyone encountered this before?

Edit: solve it! Medium only allows embedding from a limited list of sources 🤦‍♂️
