Después de actualizar a iOS 13.x / iPadOS 13.x, vemos bloqueos esporádicos con nuestras versiones recientes de Testflight. Todavía no hemos visto informes de usuarios que usan nuestra versión anterior a la 13, pero parece que no muchos se han actualizado a la 13, por lo que realmente no lo sabemos.
La aplicación es una aplicación cordova con cordova-ios 5.0.2 usando WkWebView. El derecho de protección de datos se establece en completo.
¿Me cuesta entender el accidente y parece estar en algún lugar profundo de la pila de iOS? El bloqueo es esporádico y parece ocurrir solo ocasionalmente cuando la aplicación se ha puesto en segundo plano.
Estoy buscando orientación / consejos sobre cómo llegar al fondo de esto.
