Working with Canvas support team we have tried enabling site cross-checking and uninstalling and re-installing the Clever app to no avail. We are not using the Canvas app directly on our iPad platform, we are using the Clever app to sign users in with there google accounts and then accessing the Canvas content through Clever in either the Safari or Chrome browser, both browsers have the same result of pictures not being displayed in Algebra lessons our teachers have prepared. What I have found is that much older versions iPadOS (we tested on 12.4) seem to work just fine but anything above 13.x does not work. Most of our student iPads are near the latest iPadOS version 14.2. Is anyone else struggling with this as well? Perhaps updated or changed security settings in the latest iPadOS versions are causing this but I have not found anything pertinent on the apple support site yet.
Never run into this before. We use the app or the browser and neither has exhibited this problem.
Known issue with Canvas. There's an app specific setting which can be enabled.
