Notifications
Open Settings and check that Daily reminder is enabled and the time is correct. Then open iOS Settings and allow notifications for MioCards. If permission was previously denied, it must be changed in iOS Settings.
Delete your account
Open Settings, find Account, and choose Delete account. Read both confirmation steps carefully. If deletion cannot verify the anonymous session, retry and then contact support if the problem continues. See the complete steps on the account deletion page.
