Show Your Work No Visual on iPad for students

Certain students when filling out a GoFormative on iPad using Safari, when they click on the Show Your Work it shows a blank Canvas. They can scribble on the Canvas, but nothing shows up as the scribbles we are inputting. The scribbles show up when it is minimized but not in canvas mode. Has anyone else had this issue as well?

Hi there, thanks for posting in the forum? What generation iPad and what version Safari are they using?

It is an iPad 7th Generation on version OS 13.7.
