How does the WhatsApp web client still work with the latest iOS update (SDK version 13.0+)?
问题 So dark mode support was added to version 2.20.31 (released in March of 2020) of the WhatsApp client. This is an iOS 13-only feature, and from the look & feel it appears to be a fully native implementation. I think it is safe to assume that the app is now being compiled with iOS SDK 13.0 or above. The thing is, as of iOS 13, Apple now requires the native call screen to be shown whenever a VoIP notification is received - otherwise, the app will not receive any further VoIP notifications. In
