List of 3rd Party Apps fails with original firmware on ASUS Zenfone2

Please create a sticky for this, as the list will surely grow longer with more regrets for not buying a Samsung:

- Amazon App Store / Underground App.
- Starbucks Rewards App.

Lost all purchased apps in Amazon Underground App on Zenfone2

Amazon Underground App would just scan forever under CLOUD section on the Zenfone2, none of my previously acquired apps would show up.
