A workaround has been put in place which blocks students from using Stack if the problem happens (this should stop anonymous submissions from happening (so there's not a difficult reconciliation process behind the scenes).
We have not had any calls about the issue for a significant period.
Accessing Stack through Learn sometimes drops user login information
The problem is impacting a small number of users in Maths but it's a still a bigger issue because it's assessment related and there's no audit trail on who has completed the assessment. A workaround has been put in place to stop unauthenticated users from sitting any assessments which should make the problem easier to manage.

Notes for future reference
We are still working on this but unable to replicate it. Doing data collection from other systems - although it doesn't seem to be impacting users any more.
