Hello,
First of all yes, this is the right place to post issues with the plugin. For issues that are about the main plugin you may also post at the wordpress.org forums, but here is fine too.
As for your particular issue, the UIs will only show when there is at least one adapter that is in “responding” status. So this is expected behavior.
You may also refer to the “troubleshooting” section in the PDF documentation, under “I do not see the UI elements in the frontend.” I try to keep a record of the most common issues people face.
regards
Alex
