Flysky Reciever is bound, but the drone doesnt recieve input

Hello everyone!
I recently broke my receiver, and got it replaced. I plugged the new one into the drone and bound it like normal. Everything works, and nothing weird happens. Only when I tried to power up the drone nothing was happening. I plugged it into betaflight to see the input, but I see that there is no input coming from the radio. But the radio says it is bound to the receiver… Does anyone have a clue what it could be… The radio is set to PPM mode, and the previous receiver works fine. The drone i have is a ImmersionRC Vortex 250 and the Radio is a Flysky Fsi6. Thanks a lot!
