Thanks for a very informative article!
I gave you a 4* instead of 5* simply because I personally prefer (as the years go by) to have the pertinent information right there at the top, with the entertaining description of how you found the cause below - simply to save time if all I want is a reminder of the facts.
But, the 4* I gave are at the top of the 4* band 😀

All--thanks for the kind words. Mister.magoo--point well taken. I will preface with a summary if I ever write another one of these.

Although this article is over 3 years old I came around by accident today. Very interesting and - to be honest - I didn't had it on the focus so far.
I gave 5 * because of the very well and easy explained root cause of the scenario.
