You have turned on your camera and opened Athlee Coach, but the camera is not there. Almost always this means your iPad and your camera are not on the same Wi-Fi network, so start by making sure you are connected at all.
Turn the camera on, wait 60 seconds, then open Settings → Wi-Fi on your iPad and connect to the network your camera is broadcasting.
If you are not sure which network that is, or there is no Athlee network in the list, start with What to Do If You Can't See the Athlee Wi-Fi. That article walks you through reading the Wi-Fi list and tells you what each result means. Come back here once your iPad is on the right network and Athlee Coach still shows no camera.
Turn the camera off, then on again, and wait 60 seconds before reopening Athlee Coach. A camera that missed its network at startup will usually pick it up on the next boot.
Two things to rule out, in this order:
You would normally never connect your iPad to CamCom-XXXX, and you cannot stream over it. This is the one exception. It is the only place you can ask a camera why it did not join your pool Wi-Fi.
CamCom-XXXX. Use the same password as your Mobile Athlee Wi-Fi. If you have not changed it, that is 12345678.When you are done, reconnect your iPad to your pool Wi-Fi to start streaming again.
If one or two cameras appear in Athlee Coach and the rest do not, the problem is usually with how the cameras found each other rather than with your iPad. See Not All My Cameras Show Up in the App.
