Thank you so much for your concern.

As the draft data is stored in the blockchain, it should not actually be lost.

Yes, it does store.
Maybe I am not clear enough to point out the issue. As I was doing some last edits, it kind of stuck. And then when I updated it again... Everything was lost. I don't know maybe something I did. But sometimes it happens when I'm trying to edit, even before posting the blog.
I even noted down the time of this glitch and was wondering if it happened to anyone else too. Lol

• I don't know much about the technology.

As if I know heaps 🙈

Definitely going with the C &,P option in the future. It was a lesson learnt
