I have 2 kitchen sinks with a garbage disposal, and the water drains from 1 side to the other, then it is slowly drains completely. I checked the S connection below with no clog. Please advise. Thanks

You have a "S" trap? Sounds like you have a blockage downstream from the trap.
Try this, Remover the trap and send a snake down the pipe. Put out at least 15 feet of snake. Reassemble and test. Drain better now? Good luck, Tom
