Everyone in the e-learning community needs to be aware of this issue. Chrome browser version 80 is about to go live in the first week of Februrary 2020. If your users or your organisation implements this browser version, but your LMS is not updated to cope with the change to the way the browser works, then you may be deluged with complaints from users because their course modules were marked as incomplete or failed, even though they correctly completed and passed them.
If your LMS administrators are not known to be "on the ball" make sure you pass this information on to them and record the fact that you did so. Then if the problem hits, you can maintain your innocence.
