A few things to try.
The theme isn’t showing up
Make sure the extension is enabled in Chrome and switched on in its popup. It works only on HTTPS Math Academy pages. Refresh the page after installing or reloading the extension.
How do I return to the original appearance?
Switch the extension off from its popup. You can also choose System, Light, or Dark there. Command/Ctrl + Shift + L switches light and dark when you’re not typing in an editable field.
Where did my drawings go?
Drawings and geometry-tool positions belong to the current page and reset when you reload or navigate. Use Command/Ctrl + Z to undo a mark, erase, or clear action before leaving the page.
How do I move or draw with the instruments?
Drag a ruler or protractor by its clear body and rotate it using its round handle. Enable Draw to trace the instrument edges. The compass keeps its span when you move its pivot. Press Escape to turn the active tools off.
Why don’t all cards have a PDF button?
Printing is available for eligible tutorial, worked-example, and noninteractive topic-reference cards. Question and answer cards are intentionally excluded. The button opens Chrome’s print preview, where you choose Save as PDF or cancel.
Do I need a Math Academy subscription?
You need your own Math Academy account and access to the lessons you want to use. Math Academy Glass is a free, independent extension and doesn’t provide subscription access.
A useful bug report includes…
