I have the free dropbox account. I received an email saying that my account will be closed on Thursday because I haven't used my account in over a year. This is crazy. I am in my account everyday, working with files. I stay signed into my account and do not sign out. I am signed in on 3 different devices. The email says I have been signed out on all devices in preparation for account closure. As far as I can tell, I am still signed in on all devices. The email says it could be contacting me regarding an unused account, but the email is correct for the account that I am using. Do I need to sign out of my account and back in for it to register that my account is active? Wouldn't adding , removing, and editing files show activity?
