Viewing and commenting on proofs



Has anyone else had trouble viewing or commenting on proofs lately? When I click on the proof icon for a row with a document attached, the document I am trying to comment on appears to be loading but never actually loads.

I've attached a screenshot below.

Just to clarify, I am using a free account and my company has granted me "edit" access to this sheet. The sheet owner has also clicked the "Allow Download" box.

Thanks in advance for your help!
