Liftmaster sub 300 set up

[Iceice54]

Hi , can anyone please help me with setting up my gate system? Have installed two sub 300 motors and powered up for 1st time , having trouble timing the two gates together, and can’t get it to respond to the remote controls ?

Have managed to program the two gates to open and close together with the soft close function working but still can’t get the remote to work, seems to be a photocell problem, anyone?
