We are using the Canvas Student app (version 6.4.2) on iPads (iOS 11.3.1).
When we try to annotate a PDF with the Text Tool it is applying a white background. The white background at time overlaps the document's information underneath it. We would like to be able to change the Color Presets to be transparent like all of the other annotation tools.
In the past, it used to be transparent.
How can we change the Color Presets for Text?
