I lost all saved versions from 2018-12-09 00:00 UTC+8 to 2018-12-09 05:30 UTC+8!!!
I am sure the versions were uploaded to Expo as I have been testing on my Android via Expo Client app in the previous 5 hours.
Suddenly, the Expo Client shows the versions 5 hours ago. And I lost all code changes in the previous 5 hours!!!
Finally, I do everything again on Expo Project locally.
