We are aware that you can edit the creation date. That is not the issue. The issue is the UI change in this new release to how the date is entered. You were able to type it in or select from the calendar prior. Now you are only able to select from the calendar.
One update to my original post. I was not aware, or the UI was updated after my post, that you can actually select the year. It is not intuitive to see that this is possible as the year field is not noticeably designated as editable in the UI. It wasn't until I saw a video on this that I learned it is editable. And only if you hover over the year label does it change to show it is a selectable/editable value. One main flaw with this is that the scroll window only shows a range of plus/minus 7 years worth of possible selections. I.e., if I bring it up in 2021, I can only scroll back to 2013. Why it doesn't it scroll at least 100 years (a little more than a lifetime for a person)? You have to click on 2005 to then get a scroll bar that goes back another 15 years.
Let's say it is June 01, 2021 and I want to change it to Dec 21st 1997. You have to click on the year, scroll to 2013, select 2013. That brings up June 01, 2013. Then I have to select the year and scroll back to 2005, select 2005. Select the year again and scroll to 1997, select 1997. Now I have June 01, 1997. Now I have to click the month arrow 6 times to get to Dec. Then I have to click on the 21st to change the day. Then I have to click on the 'x' to close the calendar window. I could have typed in the date multiple times in the amount of time it would take me to click through this process.
To top it off, if you go to the Time value, if it shows 12 in the hour field and I want to change it to 6, I can click the arrows provided six times or I CAN TYPE IN 6. Why not give this same option for the calendar? Totally ineffective UI design (and I run software development for a living). Evernote, please provide the ability to type in the date.
