I'm not super sure what you're complaining about with the navigation bar. It's well within the realm of what Google uses them for. Go look at the YouTube app for example. It has a button on the navigation bar that opens a bottom sheet as well. I'd argue Sync's use of it is more in-line with the guidelines than YouTube is, since the sheet for exploring is closer to a destination than a sheet for uploading different kinds of videos. The only odd thing is being able to convert the FAB into a navbar button, but at least it's an option and not a requirement.

YouTube Music and Google Podcasts also have an "Explore" option on the navbar, they just open a page instead of a bottom navigation. He probably could convert that sheet into a page to make it more consistent, but it's probably a sheet for usability reasons.

I think the point about the FAB is good in theory when talking about what the material guidelines say, but so few apps actually use the FAB, and I think Sync's implementation which allows for such robust customization is a good and fairly intuitive use of it, even if it doesn't exactly follow every guideline. It still does allow you to pick one primary action for it. It just also gives you more options.

YouTube doesn't exactly use M3, it has some similarities, but it is pretty much its own thing. The bottom area on YouTube is also not exactly the same as the Navigation Bar from M3, the Create Button is very clearly not the same as the rest. In fact, the entire bottom area looks sort of similar to the Bottom App Bar from Material Design 2

About YouTube Music and Google Podcasts. Yeah, they have an "Explore" option, but they work vastly differently from Sync, and it isn't even a matter of being a page vs bottom sheet. On Podcasts it works more like seeing the "Everything" feed than the explore sheet on Sync.

I think Sync would benefit from removing the "Explore" option, and changing "Posts" to "Everything", and adding new targets from "Local" and "Subscribed" if they want to continue using the Navigation Bar.

OR, they could swap it for a Bottom App Bar, and remove the "Posts" button, and treat the Inbox as being a subscreen rather than a main destination
