All beta users will need to upgrade to the new Overflow app.
Overflow beta users who didn't have an Overflow Beta Cloud account will have to sign up for a new Overflow account and use that to sign in both to the app and to Overflow Cloud.
Overflow beta users who had an Overflow Beta Cloud account are advised to sign in to the desktop app and to Overflow Cloud using those credentials. This will ensure that old Shares are moved to the new Overflow Cloud.
