Don't want to speak too soon but.....all is well so far.

"The ad tracking setting is found by following the Settings -> General -> About -> Advertising path. Under that setting, you'll see something called "Limit Ad Tracking." When you encounter it for the first time, the toggle is in the "off" position. This actually means that ad tracking is turned on. In other words, your behavior is being tracked if the Limit Ad Tracking feature is turned off. If you want to opt out of targeted advertising and stop advertisers from following your online moves, switch "Limit Ad Tracking" to the on position."
Let's see how this works.
