Dynamic Links not opening app on iOS 10

[Dave]

I am just getting ready to release a new version of my app with Firebase Dynamic Links in. I implemented dynamic linking a couple of months ago, pre-iOS 10, and everything was working as expected. Now I have come to do some final tests, having built for iOS 10, I am having issues.

- If the app is installed on iOS 9 device, opening a dynamic link will take me to my app

- If the app is installed on iOS 10 device, however, opening the same dynamic link on iOS 10 will take me to my app's page in the App Store app (i.e. does not recognise it as installed).

I am using the latest version of the Firebase iOS SDK (3.9.0), and using Testflight Beta build of the app (i.e. external tester).

Anyone else seen this behaviour, or know if this is a known issue?

Thanks,

Dave

We've not seen a widespread issue with dynamic links on iOS 10. If the app is installed it should just use universal links to go straight to you app, so there shouldn't be any opportunity to go awry. Can you check your universal links set up is working as intended?
