I Installed 2 YLXD01YL ceiling lights. both of them flash/flicker every minute

I Installed 2 YLXD01YL ceiling lights. I connected to two of them at the beginning but then my nightmare began.
both of the lights always flashing/flickers. I mean that every minute or two the light turns off for less then a second and turns on again.
One of the lights is updated to the last firmware and the other has the same firmware it came with.
I also cannot connect to lights to WIFI or to the remote control.
I’m very disappointed from the product and really can’t use it. I installed one of the lights in my office room and really can’t work like that.
hope to find a solution soon. thanks.
