Hello, Hawaii

Statement:
Dear Customer,
We updated our cloud server on December 4th to improve the performance of our cloud service.
However, our new iOS APP had not been certified and released by APP Store until December 7th. As a result, some of iPhone users are likely to encounter the problem below during December 4th to 7th.
1. Old iOS APP cannot detect the camera in the process of register.
2. The camera shows offline on the old iOS APP.
To solve these problems, just upgrade your iOS APP to the latest version v2.0.6.
Sorry for any inconvenience brought to you, please do not hesitate to contact us for any question: support@tp-link.com.
