On a limited connection, I’d advise not updating whilst watching a video. It’s also possible to download a video and watch it whilst updating.
Beyond that it’s not easy to answer - as I don’t use discover, but also never do updates without paying attention, so that watching a video at the same time isn’t something I’d contemplate.

The main issues (as my best lesbian friend once chimed in with me) are the people who are rather too quick to find offence, in an aggressive way, rather than offer a correction or an explanation, or simply engage in some discussion to confirm their initial suspicions.
