Hi All, I have one tab application (say MyApp) in MS Teams which is built using React and other related technology. There is a scenario when teams user on mobile device would like to jump to a related external app (say MyNativeApp) with help of app.openLink() . Scenario 1 Action : MyNativeApp is installed, calling app.openLink('myexternal_app:// ') Output: User lands on MyNativeApp Expectation : User should land on MyNativeApp Scenario 2 Action : MyNativeApp is not installed, calling app.openLink('myexternal_app:// ') -> Promise is rejected with a similar message like "there is no handler available to open this link" 1. Now user is installing MyNativeApp and then trying #1 again, i.e calling **app.openLink('myexternal_app://**') Output: it is still returning rejected promise with old message in iOS Expectation : It should open MyNativeApp as handler is available now. Can you check why app.openLink() is not working in above case only in iOS / iPhone ? It is working on Android device and user lands on MyNativeApp correctly.

app.openLink does not detect external app deeplink handler on iOS

Hi All, I have one tab application (say MyApp) in MS Teams which is built using React and other related technology. There is a scenario when teams user on mobile device would like to jump to a related external app (say MyNativeApp) with help of app.openLink().

Scenario 1
- Action: MyNativeApp is installed, calling app.openLink('myexternal_app://')
- Output: User lands on MyNativeApp
- Expectation: User should land on MyNativeApp
Scenario 2
- Action:
1. MyNativeApp is not installed, calling app.openLink('myexternal_app://') -> Promise is rejected with a similar message like "there is no handler available to open this link"
2. ```
  1. Now user is installing MyNativeApp and then trying #1 again, i.e calling **app.openLink('myexternal_app://**')
```
- Output: it is still returning rejected promise with old message in iOS
- Expectation: It should open MyNativeApp as handler is available now.

Can you check why app.openLink() is not working in above case only in iOS / iPhone ?
It is working on Android device and user lands on MyNativeApp correctly.

Oh man. I was considering building pages in React to fix the severe communication problems caused by Teams’ poor design. But if an MVC html page in a tab behaves totally bonkers then that’s not a solution either. I think there’s no hope and I need to find an employer who values communication and NOT using Teams — and gaslighting us by saying “hybrid isn’t working” and not realizing it’s the bad MS toolkit that’s causing most of the problems. Sheesh.

@Deepak Dixit - We have tested this but on IOS after clicking on deeplink the call goes on browser to download the Teams.

@Nivedipa-MSFT Can you provide full context like what version of iOS was used for testing. I will be also preparing the video which will be helpful to understand the issue for you.

@Deepak Dixit - Could you please confirm is your issue resolved or are you still facing this issue?

We are still facing the issue. This function is working fine when you are providing a deeplink which is a kind of HTTPS link but does not work when it is a custom URL format.

Did you check by providing some custom URL deeplink like msteams:// or fb:// ?

Check below code snippet:


import { app } from '@microsoft/teams-js';

function openDeepLink(deeplink: string) {
	app.openLink(deeplink)
		.then(() => console.log('Success'))
		.catch(() => console.log('Error'))
		.finally(() => console.log('Finally'));
}


openDeepLink('https://teams.microsoft.com'); // will print Success

openDeepLink('msteams://teams.microsoft.com'); // Will print Error and not Success

@Deepak Dixit - We tested the below deeplink but its working at our end.
'msteams://teams.microsoft.com'
Could you please test this once and confirm the same?
