Hi Paul ,
I trust all is well with you all
This is Gabriele from the Docebo support team and I am sorry to hear you are experiencing a few issues with your SCORM files not completing - I understand how important this is for you and for your learners too!
I wondered if perhaps those issues are occurring on your custom domain as I have checked and I noticed there is a missing intermediate file on the SSL certificate - this can cause issues with tracking course completions.
We posted a Community article on this topic too which I would suggest reviewing:
I would suggest flagging a ticket with the Docebo Support team so that we can advise you on the steps to take to rectify the errors and hopefully resolve the course completion issues you have been facing.
I hope this helps!
Thank you
Gabriele
