Hi @Feilim - hopefully Evolve Support will have responded by now… but for the benefit of others:
If you have the setting Launch course in popup window? enabled in Evolve’s Advanced SCORM publish settings, you will need to change a setting in SCORM Cloud so that it doesn’t also launch the course in a popup - as having two popup windows will prevent Evolve from being able to find and connect to the SCORM API.
The setting in SCORM Cloud is Course Properties > Launch Behaviour > SCO Launch Type and needs to be changed from New Window to Frameset.
