Thanks for your reply @catchlight @realtm
Unfortunately the problem still persists, The cache wasn’t the issue I’ve also tried to visit the site from a different device. And the latest track is one month old so that shouldn’t be the problem either. The strange thing is that when using the random method the latest track appears and it works fine.
I created a test page with the the shortcode as follows: [soundcloud user='username']
and this time the soundcloud player loaded but it said Oops, we couldn’t find that track. I also tried with a different username but the result was the same.
I hope this information was useful in order to identify the problem.
Thank you.
