Also AoN reliability and performance track record is pretty spotty, although it has improved slightly lately. Feels very amateur-ish.
Let us be honest, any website officially connected with Paizo is a hot mess. This website and forum run poorly under any load and the storefront makes DTRPG look like the pinnacle of web design. They need to get a technical team to develop apps and web infrastructure in-house.
To be fair, Archives of Nethys was also just one or two people creating a fan website until a couple of years ago. And even now, it is still just a group of independent people working on it - they just now have an official license agreement.
Back in the PF1 days I always used d20PFSRD because of how awful AoN was. There's no excuse for AoN to be as bad as it is even if it is mostly a small team working on it.
