Are there any limitations on how many times you can watch a downloaded video?

Yes, there are some limitations on watching downloaded videos from YouTube Premium. You can only watch downloaded videos up to 4 times within 30 days, and then you need to reconnect to the internet to verify your subscription again. After that, you can download the video again and watch it up to 4 more times within the next 30 days.

It's also worth noting that the availability of downloaded videos may depend on the content owner's preferences, as some videos may not be available for download due to copyright or other restrictions.

Additionally, downloaded videos are only available on the device you used to download them, and they will expire if you cancel your YouTube Premium subscription or if the video is no longer available for download.
