Registrei-me com sucesso no APN e recebi o ID do token. O problema é que, quando envio uma notificação do console do Firebase, recebo um erro

Certificado APN inválido. Verifique o certificado em Configurações

Estas são as etapas que segui para atribuir o certificado .p8 APN ao Firebase. Estou testando o aplicativo em um dispositivo Iphone. O que estou fazendo errado?

criou nova chave emhttps://developer.apple.com/account/ios/authkey/baixou o arquivo p8obteve o ID da equipehttps://developer.apple.com/account/#/membership/carregou o arquivo .p8 no console do firebase em Configurações / sistema de mensagens na nuvemno meu .xcworspace em Destinos / Recursos / Notificações por push: LIGADOO arquivo myproject.entitlements contém o desenvolvimento de APS Environment String.NOTA: No developer.apple.com, em APP IDs, se eu clicar no ID do myApp e rolar para baixo, o Push Notifications Configurable & Development é exibido em amarelo e não em verde.

Algumas pessoas no SO sugeriram que eu deveria criar uma nova chave no developer.apple.com. Fiz isso, segui o mesmo processo acima e o mesmo erro.

EDITAR

O token gerado pelos APNs no lado do cliente é semelhante a:cUEPUvXjRnI:APA91bGrXvRpjXiIj0jtZkefH-wZzdFzkxauwt4Z2WbZWBSOIj-Kf3a4XqTxjTSkRfaTWLQX-Apo7LAe0SPc2spXRlM8TwhI3VsHfSOHGzF_PfMb89qzLBooEJyObGFMtiNdX-6Vv8L7
