Question about Midland Bike Guardian Wifi

I did receive the camera and accessories. After installing the recommended SD card and installing the app on my phone, I was hoping to connect to it. But it's impossible. The camera deactivates after a few seconds, no explanation of how to use the app (half in Chinese), instructions too small to be usable. I'm very disappointed with my purchase. I am very disappointed with my purchase. I do not recommend the product.
