I don’t have to do this anymore. Here are my steps for getting my Enpass data to the app on my iPhone.
1. Create a backup file on my Windows computer (settings gear icon, Vaults, Primary, Back up Now)
2. On iPhone, settings gear icon, Advanced, Erase Everything, Resore Existing Data, WiFi
Then I just type the link from the iPhone screen into a browser on my Windows computer and follow the directions from there.
If someone knows of a better way please post it here. Thanks!
