The /mobile command suggestion and iOS/Android QR code download dialog were removed in favor of the Remote Control feature. The entire YG1 component with iOS/Android tab switching and QR code rendering was deleted.
Evidence
Removed mobile dialog (search for "mobile-app" in old version) — YG1
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
