I've been trying to get my Fenix 2 syncing properly with GCM for the past couple weeks and I noticed something strange. The app in the play store is version 3.1, but there are APKs out for 3.3 and 3.4. I'm currently running version 3.3 becuase syncing works for me in that version, but I forgot to turn off auto-update and found that version 3.1 is what got downloaded.
Did they change the version numbers or did they rollback several versions?
