[ARCHIVED] Folded corner page (earmarked page) with frown face image under assignment link

[SN6]

What does it mean to have a folded corner (earmarked page) with a frowny face inside mean? I am new to canvas and I am just starting to upload my assignments, but every time I do, below the link I see this earmarked, frown face image.

That my friend is your best friend, Grammarly. He smiles when you spell or punctuate correctly.

I believe so, anyway.

No - It turns out it was the AdBlocker! It was blocking the files from loading. Ugh!

Neverseen that before.
