Hi there! Thanks for taking the time to reach out to us! I hate to hear that you are having some issues with the accessibility features of the app. To make sure I understand, you are able to find the show with no issues using the search feature, but in the guide is is missing if it is past the start time?
When you are on the computer you should have a Watch Live button in the top corner, and once you select a channel in the guide, you should be able to click watch on the right side of the screen to start a program.
We can definitely understand that. I will be forward this feedback to our Engineering Team to review on the iPhone. We do want to make sure that all of our customers can enjoy the same features on the app across the iOS devices.
