Storyline not talking to LMS?

Hi all, I have a very simple linear course with a short quiz at the end of 7 questions and pass mark of 80%.

We're running this - along with other SL2 courses - on a Totara LMS. There are a multitude of settings on Totara, all of which I have tried to no avail. The most important ones I presume are that:

• Completion tracking is enabled
• Activity completion is of the SCORM module
• The required minimum score is 80

Unfortunately the LMS refuses to recognise subsequent attempts after the first - even if it is a pass. Also subsequent attempts are not logged in the reporting section, even though the time last accessed is correct.

I have had success by telling the LMS to force a new attempt each time. The grade reporting then lists each attempt and accepts a pass. Unfortunately this also means the learner cannot return to the course to continue from where they left off.

I have tried publishing from SL2 using Passed/Failed & Passed/Incomplete.

Any ideas anyone?
