Standard Notes License Is Incorrect
I happened to be looking at the Standard Notes GitHub repository and noticed that the license was changed a few months ago from AGPL-3.0 to BY-NC-SA 4.0, however, on the application page, F-Droid still shows the license as AGPL. It also appears that there have been F-Droid builds of Standard Notes after the license change, see the LICENSE
file of the source of the 3.171.12 build, so I'm assuming that the application metadata should be updated to reflect the new license.
