After clicking I am done to end a VideoMode session, the processing takes a very long time and I cannot start a new VideoMode session.
In most cases, this is a camera connection issue that you can solve with a few clicks.
1. Make the camera use 5 GHz.
You can check this in the WiFi list on your mobile device, see example in the figure below. If the mobile device uses 5 GHz, the connection is more stable.
2. Make sure the mobile devices and the camera are not more than one meter apart.
3. Disable Private WiFi Address for the camera network.
a. On your mobile device, open the Settings and select WiFi (or named in a similar way).
b. Tap the info icon next to the camera's network and select Private WiFi Address (or named in a similar way).
4. Turn auto-join off for all other known networks on your mobile device.
5. Make sure the app remains open and your screen stays awake.
6. Make sure you use a V30/UHS-I A2 card that was formatted in-camera.
7. Make sure that the camera battery is fully charged.
8. Prevent the camera from getting too warm.
