I have a number of apps that are currently built with ionic 3.
cli packages: (/Users/lester/.nvm/versions/node/v8.11.1/lib/node_modules) @ionic/cli-utils : 1.19.2 ionic (Ionic CLI) : 3.20.0 global packages: cordova (Cordova CLI) : 8.0.0 local packages: @ionic/app-scripts : 3.2.3 Cordova Platforms : android 8.0.0 ios 5.0.1 Ionic Framework : ionic-angular 3.9.8 System: ios-deploy : 1.9.2 ios-sim : 8.0.1 Node : v8.11.1 npm : 6.0.0 OS : macOS High Sierra Xcode : Xcode 10.1 Build version 10B61
What I am seeing on some Apple devices is that once the phone/tablet is updated to ios 12.4 that the apps will attempt to launch. I then see the initial screen for a few seconds before it disappears.
If I delete the app, download, and install from the app store it will then work again.
Has anyone else seen this?
