Even though Verizon officially announced that Android 6.0 Marshmallow was rolling out to their Motorola Droid Turbo 2 devices, apparently, that didn't mean "all" Droid Turbo 2 owners. For some reason, Big Red did not push the OTA out to every Droid Turbo 2. In fact, just yesterday they "re-announced" the deployment of the OS update for the Droid Turbo 2.
The versions of the update which are possible for the two different revisions of the Droid Turbo 2 are: SU1A: 23.31.24.kinzie_verizon.verizon.en.US or SU1.75B: 24.14.12.kinzie_verizon.verizon.en.US. No explanation was given on why this has been the slowest rollout of an OS update ever, but at least they let people know that they weren't forgotten.
