Hi Ron
Thanks for responding so quickly.
Has this worked with your combination of Moodle and Xerte previously or is this the first time you are trying it? - First time trying it out.
As a general rule now, whether for SCORM or LTI/xAPI, you should include a stop tracking page at the end of your LOs. Have included this.
Also to eliminate variability test with a definite student account rather than just changing role to student. Tried it with a test student (not just a change in role).
Test with a couple of different browsers e.g. Chrome + Edge or Chrome + Firefox. Tried Chrome, FF, Edge and Safari.
Under the privacy section in Moodle for your LTI resources there's an option labelled 'Accept grades from the tool' is that checked? Yes, this is selected.
Thanks
Yvonne
