I also have this problem. It just keeps loading symbol until I take off lazyload option. Then the playlist shows but the accordion does not close.
Sorry for late reply,
have your issue fixed ? please reply if you still need some help.
Using WP version 4.6. Also had the above issues in previous WP version before upgrade.
Under Accordion Options > Enable Lazy Load. When toggled to “No” Accordions now load on pages. Went through each Accordion and switched this option to no and all load.
While this seems to have fixed the issue, please advise on the accuracy and root cause. Thank you.
