I'm using Animate and 18.104.22.168 SDK.
Publishing simultaneously to iPhone X running IOS 12.4.1 and iPhone 6s Plus running 13.1 Beta. Animate recognizes both devices.
iPhone X running IOS 12.4.1 installs correctly but I get error message regarding iPhone 6s Plus running IOS 13.1 Beta:
"IPhone 6s Plus: The device has encountered an unexpected error. Error connecting to your device!"
I can install .ipa to iPhone 6s Plus using Apple Configurator 2, and remote debug works from Animate after install.
