Having a problem with the latest build of Chrome on one of our sites. The cart session is getting wiped every time a user navigates between pages. I have been able to reproduce it. This is only occurring in Chrome. Firefox and Safari are unaffected. Also, it seems that this problem may have started most recently with update to the latest build of Chrome, which was rolled out within the last 10 days. I had seen this same problem on this specific site back in September of this year, and determined at that time that it was also related to a specific build of Chrome. When it happened the first time I was able to resolve it by updating the Chrome browser to the newest build back then (early September). Now it seems that the problem is back, but Chrome is updated to the latest build (70.0.3538.110).
I have been unable to recognize any obvious errors that would be causing this issue. Please investigate as soon as possible and let me know if there's anything that I can do on our side to resolve this, or if there's something you need to do on your side. This is occurring on only one of our sites, and not another, but both use FoxyCart.
I will whisper affected site URL and login credentials for you to test.
