FYI I am in the middle of resolving this with SCC Support. The new HTML annotation tool does not work for me fully in either Firefox or Safari on the Mac laptop.
The old Flash annotation tool is no longer an option in the 10-per-page view of anyone's chart list, but it does appear as an option at the bottom of each chart when one clicks on a chart to see it alone, such as when one adds new parameters, dates, etc. to the chart.
A longer road to get there and back, but workable.
Thanks for your help, Cush.
