I seen a few posts dating back as far as 2021 about this feature being added. Looks like from other posts it was added on your old platform then you migrated and this feature doesn’t exist on your new platform. I am disallowed from posting links to the posts but they can be easily found. I have found where people have asked for this feature back in July 2024. Any updates on this feature getting added as it would be very useful and I have had it on most other training platforms I have used like cloud guru etc.
It would also nice in the future to be able to have a feature to flag certain videos/labs for revisiting. I can only speak for myself but I go through material more than once and it would be good to have an option to go back to areas I feel are important.
