So if I got this right, there is no way to edit a Voicenotes page after publishing it.
I mean, you can edit it, but to do that, you have to unpublish a page, edit the original transcription, and then publish that again.
I just did that and what happened was that an old post that I edited and published again just got, marked as a post published today.
In other words, the creation date online changed to today and that's not really ideal.
