We recently made the change in response to significantly increased Google costs to us in running the maps on the website.
You can use the site ad free buy purchasing a subscription. The options for this will come up when you click on the "Remove Ads" button. Alternatively you can continue to see ads.
Hope this helps,
Ad's are an annoying part of the internet and life. I'd expected an answer similar to yours.
Google seem to want to control everything, and make it difficult to use the internet without some form of control.
I always click on the "report ad" box in the ad and fill in one of the choices to report to Google. It makes no difference if I say I've no interest in the ad or I've seen it many times or whatever. the next time I bring up Planefinder the same ad is there, although they say " We'll try not to show that ad again". Not exclusive to Planefinder of course. So now I use an ad' blocker in my browser. So it rather defeats the object.
If I'm not interested within 20 seconds, any extra time is not going to make me any more interested is it?
Perhaps you could move to a more ethical partner.
