For anyone wondering where the avatar items are, here's an update from Niantic Support:
"Trainers, due to quality issues with the avatar items inspired by Eternatus, they will not be immediately available for sale after the Pokémon GO Fest 2025 Max Finale. The website has been updated to remove affected items and we will provide an update when these items are available, thanks for your understanding. https://pokemongo.com/gofestmaxfinale #PokemonGO"
