To protect our platform we’ve rolled out extra measures to identify and catch fraudsters. One of these measures is limiting the number of devices individual accounts can be registered to. While we all may need to change devices from time to time (if we’ve lost a device or got a new one for example), frequent changes can be correlated with fraudulent activity. This is why we monitor and limit the number of devices linked to any account.
If you need to switch your app to a new device, please get in touch with our customer service team on help@dozens.com and they’ll be able to assist.
