I know I'm digging this old post for a good reason - I thought it may be more appropriate than write a new one. I managed to get the profile picture show through doing Hangouts profile picture change however the cover photo still won't update and I am stuck with the default one - anyone found a solution? Seems that Play Store is the only place where this gets updated. Keep, Calendar, Inbox - all won't push the cover photo to navigation drawer. I'm on OPX 5.1.1. I cleared cash, restarted, updated through G+ app - still nothing...
