What are the pros and cons with an overflowing horizontal scrollable nav bar?

On the team with designers and coders at my office, we're currently having a discussion about horizontal navigation bars when they overflow on mobile. This is not a discussion about using cards that are scrollable, like in the Netflix app, but rather in a menu/sub menu.

We took a look at what Google is doing and they fade out other options that are not visible.

But what happens when the screen size is smaller than that?

Suddenly, there's no indication whatsoever that there are more options.

That's my biggest concern with these types of solutions. Other things I'm worried about are accidental edge swipes and back navigation. Wouldn't a "More" menu be a better solution?

What are your thoughts? Are people used to this type of navigation? Do they actually use it? What are the options?
