This application has had numerous technical issues, including failure to sync and inability to back up to the drive. I subscribed to a plan that allowed usage on both mobile and PC; however, I was unable to use the app across both devices due to the syncing problems. I contacted customer support in the meantime, but the representative I spoke with was extremely unprofessional. As a result, I have unsubscribed and removed the application. If anyone can recommend a more reliable app that works sea

Customer support is very responsive. Update: The application is experiencing technical difficulties, resulting in multiple failed login attempts. Additionally, users are not receiving emails when the "forgot password" option is selected.
