Since upgrading my iMac to High Sierra opersting system about2 weeks ago I am having A LOT of issues with my Xfinity internet and Email! Am I the only one? Chats with Xfinity reps seem to indicate engineers are working to streamline the High Sierra OS with Xfinity. When I click on a news item on the Xfinity page, a pop up screen comes up with only text- no photos. Also, sometimes the video articles will play and sometimes they won't. The video ads always play. Also, on the Xfinity page if there is an article about a recipe when I click on it a pop up screen goes to text (no photos) with only the directions and not the ingredients for the recipe. On my Emails, when I click on an Email, sometimes a pop up screen comes with only the title of the message, date of message and sender and my name- no message and no way to reply, etc.!! Sometimes, if I BCC to myself on a message I reply to (that I actually was able to open and read) when I click on the copy of the reply I sent myself a pop up screen comes up like the one I mention above. Also, on some Email messages I click on to read sometimes a pop up comes up with a grid listing messages sent to trash when size of the message!!
I am VERY irritated with this AND the fact that the Xfinity reps I have online and verbally chatted with cannot help me "fix" whatever has happened. Can anyone help me solve these issues? Is this something Xfinity engineers recognize that they have to correct for Apple High Sierra OS users?
I am running High Sierra v10.13.1 on an iMac, and I am not having the issues you are describing. I use Chrome most of the time, but I also use Firefox and Safari for different things sometimes.
