Some Reddit users have noticed that they can’t sign-in to their accounts anymore on mobile, as the option to do so has been removed for them. Reddit has made it difficult in the past for users to access the site on mobile in browsers. The company’s main intention is to get users to use the official Reddit application instead.
I think that is the dev shutting down the app for the blackout.
Nah, the dev already said they’re not shutting down the ApolloApp subreddit because it’s how he’s communicating with everyone (per his most recent post on there). It wouldn’t make sense for him to shut down the app.
