Disabling and re-enabling the plugin seems to have resolved the carousel issue. Just disabling the CSS options and empty caches didn’t help.
Now the only issue seems the button but I don’t think it’s the plugin. I’ll have to dig that further. 🙃
PS the site is also running on Cloudflare APO
not sure what is breaking the button, but it seems like the carousel issue is caused by the CSS options. If I disable the options and empty the cache it seems that the carousel works fine on mobile. It I activate those options the issue is back. What I find interesting is that it’s not happening on every page, but just on some.
