My two quotes that you are referring to, appears somewhat contradictory.
But it must be understood that in that moment, the definitive solution had not yet been found. In my ticket I requested you take a look at user benfititas post in this thread, because I thought that the most probable cause to broken sites were related to GoodByeAds, and I thought that benfitita were on to what I thought were the most probable cause to my broken sites. And in the end this proved to be 100% correct. Since around 29 or 30 June when I disabled all GoodByeAds while leaving all other lists enabled, those sites that had been broken, have since that moment always resolved 100% correctly, including images or graphics drawn in from subdomains.
Yes, before disabling all GoodByeAds, I was able to access those sites when using a thirdparty DNS when connected to AirVPN servers, with the troubled sites not broken. Using thirdparty DNS resolvers are thankfully no longer necessary, as this is not recommended to do when using any VPN service. There is another positive thing that also were solved after the solution were found:
In my support ticket, before having disabled GoodByeAds, Ads sometimes were loaded on the broken sites, and at the same time, the sites were not broken! This I wrote to you, I perceived as very strange, almost spooky. Because sometimes when connected to the same VPN server, the sites were broken and no ads were loaded, and other times ads loaded but other elements such as images also loaded, so the sites appeared not broken, except that all ads also loaded, which shouldn't happen since all DNS Lists were enabled. Now since 29 or 30 June, not only has the sites loaded perfectly, but ads also almost never shows up anymore as well.
I actually would suggest that you remove GoodByeAds from your DNS lists options, because now on my account with all lists enabled except GoodByeAds, no sites are ever broken and I almost never see ads. Exactly how I (or we) would want it to work.
Benfitita led me to the solution. And thanks to him/her for that 👏✌️
