CarPlay CPGridTemplate – buttons show in a row, and limited to 9 buttons

Hi,

I’m working with CPGridTemplate in CarPlay. According to the documentation, it supports up to 9 CPGridButton objects and should display them in a grid (up to 3×3).

However, I’ve run into two issues:

Row instead of grid

When I add 4–6 buttons, they don’t appear in a 2×2 or 2×3 grid. Instead, they are shown in a single

horizontal row. Even 9 buttons do not appear in a 3x3 grid.

More than 9 buttons

My use case requires more than 9 icons, but it looks like CPGridTemplate ignores any additional buttons beyond the first 9. Is there any supported way to display more than 9 buttons in a grid, or is pagination/multiple templates the only option?
