Same issue- any support with this?

@KarlSearl The only workaround for this issue is to set a fixed width on the element inside the carousel view. Depends on your needs, but you can obtain the width size of the screen and set it to each row of the collection view, please take a look at the blog post I created to obtain the screen sizes, and how I use it to set a fixed width or size of elements on the UI, you can either use it on a ViewModel and then binding it, so you can render it on the CollectionView row.
