Após a atualização para o iOS 13.x / iPadOS 13.x, vemos falhas esporádicas com nossas compilações recentes do Testflight. Ainda não vimos relatórios de usuários que usam nossa versão lançada antes do dia 13, mas parece que muitos não foram atualizados para o dia 13, por isso realmente não sabemos.
O aplicativo é um aplicativo cordova com o cordova-ios 5.0.2 usando o WkWebView. O direito à proteção de dados está definido como completo.
Eu tenho dificuldade em entender a falha e parece estar em algum lugar profundo na pilha do iOS? A falha é esporádica e parece ocorrer ocasionalmente quando o aplicativo é colocado em segundo plano.
Estou procurando algumas orientações / dicas sobre como chegar ao fundo disso.

Consegui reproduzir esse problema de forma consistente no iOS 13.1. Mas testei hoje no iOS13.2 beta 4 e não consigo mais reproduzir esse problema. Sugiro reverter o nível de proteção de arquivo para concluir e testar a versão 13.2 beta mais recente.

Atualize o dispositivo para o iOS 13.2, se possível. Instalei o iOS 13.2 e não consigo mais reproduzir esse problema. Não alterei o nível de proteção de arquivos para
