Apparently now with iOS 26.1 if you have .tabViewBottomAccessory { } you get a pill shape floater all the time. That was not like that in 26.0.
iOS 26.1 and tabViewBottomAccessory
Tab bars accessory views stay visible across your app, this was introduced in iOS 26.0. Please review Get to know the new design system to explore the new design system and key changes
I've seen this as well. In 26.0, providing a conditional statement around the contents would hide the bottom accessory view, now it is shown constantly.
