Using the iOS Shortcuts app I have created a Shortcut to jump Channels on my Apple TV by 4 minutes (e.g. to skip an ad break when behind in the timeline).
I am using the following URL as per the API docs, calling it via "Get Contents of URL (POST)":
Most of the time this works as expected, jumping the full 240 seconds (4 minutes).
However, for no apparent reason, sometimes it jumps a much shorter length of time, not sure how long but guessing about 30 seconds. Despite being more than 4 minutes behind in the timeline. So I end up having to then manually skip through the rest of the ad break.
Any idea why this is happening?
