First of all, I would like to share that the first beta of Enpass 6 was released as a standalone app and was installed as a separate app on your device parallel to the existing Enpass app. But we've terminated the updates for Enpass 6 beta standalone app and recently pushed a new beta version over the current Enpass 5 app. Due to different data locations on the cloud, it's not possible to sync.
And you are running the older beta version of Enpass on the Android device. The current version of Enpass on the Android device is 188.8.131.52. To get the new version over existing Enpass 5 app please follow these steps:
Take the backup of Enpass data save it manually on the device.
Uninstall Enpass Beta app.
Now open Google Play Store --> Open the Enpass page and scroll down to the bottom of the page, you'll find the option Become A Beta Tester --> Tap Join now button.
Now update the app and check.
Hope this helps!
