I have had three occasions where I have logout of the Android App, login and find that not all of my login profiles in the vault were not retained. In 1 of the 3 cases I had switch to new smartphone. Another time restored my smartphone to factory setting then installed login to the App/vault. Another time simply logout/login to the App and vault.
It appears that the App is not syncing my local information to your cloud. I do not use the desktop version of NIS.Nor do I have a reason to.
Currently using Nexus 5…
