You're not redirected to use the Messenger app when trying to check messages on mobile. For a bit, while on the B side, I could request a desktop site on Chrome for Android and then still use the m.facebook.com subdomain. Now that I'm on the A side, I can't use that workaround. I've been told other m.facebook.com wrappers like Tinfoil were affected by this as well.
