SS7.1 YouTube video not starting at correct timestamp

Site URL: https://www.zachkononov.com/press-media

Hi all!

I'm trying to embed a YouTube video to my website with a URL that starts the video at a specific timestamp. I pulled the URL from the YouTube video at that specific timestamp (2:06), but when I play the embedded video, it always starts at 1:45. On my boyfriend's laptop, it starts at 0:00 sometimes and 1:45 other times. I have changed the URL to different timestamps as a test, and it still always starts at 1:45 or 0:00. 

The page with the video is here: https://www.zachkononov.com/press-media. The video in question is the second video on the left, at bottom of the page. 

Regular video URL: https://www.youtube.com/watch?v=4-sJCxXyHg4

Timestamp video URL: https://youtu.be/4-sJCxXyHg4?t=126

I'm having this same issue. Is there a solution?
