We have identified an issue in a recent update that is causing failure in the startup of Enpass (store-version) on many systems. We are sorry for the inconvenience caused. There are few things you should know:
1. DO NOT UNINSTALL your copy of Enpass, if your data is not backed up with cloud or manually.
2. Do not worry, Your data is safe. You will be able to access it normally, after the fix update.
A fix update is currently rolling out in Microsoft Store. It should be available within few hours. Thank you for your patience.
