I have a ZTE ZMAX PRO on 6.0.1. I have 2 accounts (2 different email accounts which also show up in the Play Store.) and I'd like to switch it back and forth as needed but can't seem to figure out how to do it. Can anyone help with this? I've tried changing it at the Play Store and in settings on the phone but neither seems to work. Am I missing something. Any help would be appreciated. Thanks in advance.
