This has become a kind of common practice in mastodon apps, in particular, and was mentioned in the release notes. It may seem awkward at first, but it becomes super convenient 🙂
When I didn’t even find anything for it on the account management screen, I felt really stuck.
My suggestion would be to add a control there. Everyone will inevitably find that.
The existing control, long press on the tab bar, can remain. It’s a good shortcut, and as long as it is just a shortcut and not the ONLY way, it’s okay for it to be less discoverable.
I remember it during WWDC. You can use it to highlight new app features or sorta like a tutorial for when it’s first downloaded. Pointing out key app features.
