problems with upgrade to Safari 12.0
I've had problems with a couple of websites not working properly with the latest version of Safari. The first problem I noticed was with the Washington Post website. My computer was very sluggish when trying to enter comments and eventually I got a notice that they were no longer to connect with my computer. Apple support checked my computer and found it operating fine; they suggested the problem might have been unusually high traffic at the Washington Post site. But it happened another day as well, and it doesn't happen when I switch to Google Chrome browser. Then I tied to use a Harris-Teeter web site that shows their sale specials and permits construction of a shopping list. It still shows their specials but the shopping list column is not there. Again, it worked fine using Chrome. Have other users have similar experiences?
