Sync won't work with custom buttons

Hi,

I'm trying to sync two carousels and use the custom buttons UI so I can style the controls as I want but the two scripts don't seem to ant to play nicely together. Do you know how this can be achieved?

I'd appreciate any help.

Many thanks.

Start by reproducing the reported setup with two synced carousels and the custom buttons UI; the payload names no files or tests. Determine whether the two features can work together, and consider the issue done when styled custom controls reliably operate the synced carousels.
