I had drafted an email in the past, which I thought had been sent. A few moments ago, I found it in my drafts folder, indicating that it may not have been sent. Upon scrolling through it to reread it, I accidentally tapped the screen, opening the edit function, which updated the original draft date and time to the current date and time.

Given that the information contained within it is of substantial legal importance, regardless of the possibility of not having been sent, is there anyway to revert back to the original draft date and content or alternatively, some other way to validate the draft date and content?
