Sounds like Substack is using some dodgy formatting. I copy-paste normal markdown in to the raw field, without problem.

It either changed in substack or it changed in highlighter because it didn't used to happen. It has been happening for probably approaching a month now. At first I thought the formatting could no longer be pasted in, but then I realized the perfectly formatted text was there, I just had to scroll half of the way down. It is so weird.
Same thing has been happening for me the last month or so too. Probably on Substack’s end, but worth tagging nostr:npub1l2vyh47mk2p0qlsku7hg0vn29faehy9hy34ygaclpn66ukqp3afqutajft.
Oh god. These editors are so complex; I did the work to have perfect compatibility with Substack’s editor just a few weeks ago!
Thanks for the tag, nostr:npub1dtf79g6grzc48jqlfrzc7389rx08kn7gm03hsy9qqrww8jgtwaqq64hgu0 ; I’m working on the Highlighter publication and editor experience right now, so this is extremely timely.
I will make sure to have good compatibility with lasting from it again 🫡
thanks Pablo -- FWIW, the process of copying from Substack to Highlighter had been so smooth, it maybe took 40 seconds. Now it takes maybe 60, but you have to be careful not to screw it up.
