I don't understand what the issue is for you. But my Mobile Trader App works exactly with my data on computer (such as Think or Swim software - TD Ameritrade), hence NO DELAYS for me. Always has given me 'Real Time' data & quotes, and works perfectly today still. I would not post all this if it weren't true for me.
You should check again--- make 100% certain you're on the right App (as there are more than one) &/or check with your brokerage customer service about issues or restrictions that might be affecting you personally
