Help? Navigating the Directv iPad app

iOS and iPadOS

Is anyone using the Directv iPad app? I now have an iPad mini 3. On the touch 5G, I oculd easily scroll through lists of channels by running one finger down the right side to skip from 1-50, 51-100, or by letter, etc. Now I can certainly use a three finger gesture to scroll, but I seem to have to go page by page and its a lot slower.

Does anyone have any suggestions for scrolling through a large list of channels on this app more quickly? Is there perhaps an iPad VoiceOver gesture that I don't know?
