Description

Using the Launcher API for iOS, apps are receiving an extra / character that breaks functionality for the app being launched. The Xamarin.Forms.Device.Open API with the same Uri works as expected though and does not contain the extra character.

Xamarin.Forms.Device.Open Implementation

Launcher.OpenAsync Implementation

For example, this breaks Skype for Business (SFB) Mobile Uri usage..

Steps to Reproduce

1. Call Launcher.OpenAsync(new Uri("ms-sfb://chat?url=email@example.com"))
2. Tail logs for SFB

Expected Behavior

1. SFB logs indicate the url received was: url: ms-sfb://chat?id=email@example.com
2. App opens with a chat window to email@example.com

Actual Behavior

1. SFB logs indicate the url received was: url: ms-sfb://chat/?id=email@example.com
2. App opens by no chat window is opened
