It’s set to update automatically. I did check for updates after the site changes, thinking the auto-update might be days in the future, mostly due to wifi availability when the gnomes in my phone decide to process updates, but there weren’t any. Since the app didn’t update over the following weeks, I reasoned that a new app was in the creation process or, perhaps, the Medium bigwigs were waiting to see how the changes on the site were accepted before bothering to update app code. Sort of like a site beta version before app improvements. Will check today for updates that may have lost their way to my phone.
