I did as you suggested and checked the price rules. All is correct and additionally I am the only one with access and I am quite certain I made no changes. It just stopped working after the 'wonderful developers' made their most recent update.

I also did as you suggested and used a private window in Google Chrome to test the usage after checking the configuration above. Nothing behaved differently. It continues to ignore the Price Rules that have been working for 2 years flawlessly.

I am open to suggestions on how to get this very important feature to work as it used to.
