Hello Developer,
I tried the module with 5 testimonials using the slider with 1 column. I found some things difficult.
a) Unfortunately the slider doesn't start sliding automatically. Only the first testimonial is shown. Only after pointing on the module with a mouseclick the slider starts running.
b) Also there is a long delay between viewing each of the testimonial articles (approx 6 seconds).
c) The sorting isn't possible. You can sort in the backend, but the frontend sorting in the module will not change.

Joomla 3.9.15, Gantry with Hydrogen theme 5.4.32

Can you help please?
