Amphtml: amp-carousel-0.2 does not emit high trust actions on autoplay

[jaygray0919]

Here is a carousel using amp-carousel-0.2.js. Progress status fails on autoplay although it works on manual.

With amp-carousel-0.1.js both work (autoplay and manual).
Toggle ampb.in to see the difference.
We don't want to use amp-carousel-0.1.js because of the lack of smooth scrolling provided by amp-carousel-0.2.js.
Is there a work around (or better coding) for progress status with amp-carousel-0.2.js?
We'll use an alternate approach if we can successfully echo progress through the carousel.

This is due to #21171 being addressed in carousel 0.2, but not in carousel 0.1. Basically, we do not want to emit high trust actions from something like autoplay, since developers can use the action to do things that make the page jump.

We are working on a new gallery component that will have support for customizable progress indicators built into it.

There has been some discussion on whether or not we can allow some kind of changes on these events (e.g. changing colors, opacity, but not layout affecting things), but we don't have any solution at the moment.

What is your advice?

• Use amp-carousel-0.1 as we have it now and wait for better transition in a new carousel release?
• Remove autoplay from our current implementation and encourage the user to swipe thru the testimonials?
• Something else?

[nainar]

Between options A and B - it depends on how your company sees it? Do you see a lot of users using the progress indicators to swipe through the testimonials?

Also is there an A/B test that you can run for with and without progress indicator?

Closing this issue since it can now be resolved with <amp-inline-gallery>
