Thank you for contacting us. We have run into some problems with mSecure in the Play Store, and we’re hoping to have them resolved soon. Unfortunately, it will not be available for a short time while we work to resolve the issues. Please check back in a day or two, as we hope it will be resolved quickly.
@Daniel The mSecure app is now back on the Play Store, so no need to side-load the APK from our site. Here's the link to the Play Store app in case it's needed: https://play.google.com/store/apps/details?id=com.mseven.barolo
@Shiriley Your device is telling you the link is unsafe because it's an actual app being downloaded from a website. It's ok to download it, though, because you know what the app is, and who the developer is. They put in the messages about it being unsafe, because many people download apps they shouldn't from untrusted developers. Should not want to download the app from the link, you can wait because we believe the app could be back in the Play Store as soon as tomorrow.
