I found that when I pasted text copied from ChatGPT or Gemini into WorkFlowy, it didn’t work properly. In other words, it couldn’t be pasted as Markdown, even though the original text was formatted in Markdown. However, if I paste it into Drafts, I can see that the Markdown is there.
The workaround is that I use Drafts to share content into WorkFlowy.
I vaguely remember someone else mentioning this before, though I’m not completely sure.
