ProtoCast feature does not work

After being out almost a year, you’d think the app ProtoCast feature would work with a WTIU.

Still issue with MTH system

I REALLY want to enjoy the mth Wi-Fi system. But there’s always bugs and issues. If you polled 100 people about the reliability of the mth system 50% or more would say they’ve experienced issues setting it up. Lionel Legacy system hands down is WAY my reliable. GEESH MTH! WTH!
