UPDATE: Some folks on REDDIT saw it in the store on Sunday (8/10) and were able to order and receive on Monday (8/11) and activate the camera. I had checked around 3pm CST on Monday and Best Buy did not have it listed. Your mileage may vary.

Activation Warning
Folks who managed to get their hands on an X6 early reported they could not use it. Like much modern “smart” hardware, the camera is useless until it phones home and activates with the Insta360 server. There was a report of someone being able to activate and firmware update, so this may be what was in the latest Insta360 app update v2.31.1 which released yesterday.
