Please could someone help me with a problem I'm having with the YouTube app, it's driving me mad at the moment.

The problem I'm having is this, I like to listen to long audiobooks on YouTube and I use the YouTube track bar seek slider to navigate through them.
No there is a strange issue where after four hours in a video, voice-over will no longer read out the minutes it will just say four hours which is quite frustrating if you want to navigate to a particular place in an audiobook, you can't tell how many minutes you are into the book.
Has anyone else experienced this, and how can I report this to youtube Accessibility?
