Unable to "view" attached docs from email

Hello all.

It seems that for a few months now,  From Xfinity email, I have been unable to view a document before I decide to download it. Now I get this response:

"An error occurred converting the document so it cannot be displayed. Please download the file using the button below. "

I am using an iMac, and my browser is Chrome.   

If I am recalling correctly, xfinity sent out a notice stating that they might be turning that feature off, but the button is still there.  I was waiting to find out if a workaround would be offered.  

I don't want to keep cleaning out my download folder just to view docs. 

Does anyone experience this?  Have you found a solution?  

Thanks - Len
