I'm having difficulty creating a lash up between 2 PS3 Diesels; both <3 years old. Setup is a simple loop of Atlas track w/0-45 curves, TIU & WiFi unit. I have tried both my iPhone 8 Plus and my old iPhone SE which I use as a throttle. I have the same issues with both. When I place both engines on the track at the same time...there seem to be communication issues...not responding to commands; I press & release the horn and it doesn't stop, etc. Both locos run perfectly by themselves when they are the only one on the track. After cutting power & starting over a few times...both appeared to be responding separately so I went in to build the lash-up...but as soon as I hit the done button, I get a 'connection failed' error and the lash up is not created. Also, track just recently cleaned. Any ideas?
Thank you in advance!
