This is a bug encountered in the latest version of iOS 15.2. The system occasionally “warms up” the nami app to reduce start time, which lead to credentials problems. A fix has been pushed for this bug on 09/01/22.
Possible fixes
- Restart the nami app by ‘sliding it up’ on your iPhone to reboot it and forcing a new start. You should be able to log into your account again.
- Enter your recovery key to retrieve your account.
- Contact us for dedicated support.
