Sorry for the late reply, we missed your previous message somehow.
What is the status of being able to see the synchronized address book in the phone / mobile apps?
The full-fledged address book for the mobile version could be available by the end of the year. We plan to release it after the Mac/Linux version.
It looks like that the last time the android native app was updated was in 2014
Could you please clarify what version of the mobile Viewer do you use? The latest version is 11.22.0 and it was released on October 22, 2018.
Let me know if you have more questions.
