This request happens on a very regular basis by different people each time with the same type of report. Every single mobile browser, Firefox, Safari, Chrome, etc. behaves the same way. Close the session and the next time you visit, you get the nag popup. Mike is in denial. "If it doesn't happen to me, it doesn't exist." For each one of these reports, he replies the same way. "Your device's browser is broken."
Every time, I come in, do a cookie analysis and report here that the cookie is a session cookie, and not a 6 month cookie, and therefore cookies are being properly handled by being deleted when you close the browser and/or reboot the device. Each time, it is ignored. Here's one as an example:
I have a hypothesis that there is another cookie along the lines of "I'm an admin, don't bug me." that is properly being set to 6 months. Mike, create a fresh user and use a fresh browser with no Mike Lang cookies on it, and I bet you will see what all of us are seeing.
The other hypothesis is that there is an obscure User setting that sets the cookie behavior on TCF. (for that, find an old abandoned account or two)
