LDS.org Study Mode not working for General Conference on Chrome/IE

Within the past week, the Study Mode bar has disappeared for 2018 General Conference talks (English), though it's still available for scriptures. I have attempted using both Chrome and IE browsers with the same result. Previously, once I logged in to my account, the "Study Mode" bar would automatically appear at the bottom of the page for General Conference talks as well as scripture pages. Study Mode/Notes is still functioning via the Gospel Library Mobile App (Android OS). Has anyone else run into this issue? Workaround suggestions?

As a workaround, you can use the new Gospel Library Online pages at LDS.org:
