iOS app deeplinks and Firebase dynamic links don't work after app transfer

Question

I've transferred my iOS app from one developer to another. Then after first release at new account, my deeplinks accidentally stop working.

Deeplinks implemented using universal links on my own hosted url and firebase dynamic links.

Answer 1

Problem is that my Team ID changed after transfer.

1. In case of universal links on self hosted url, I had to update my apple-app-site-association file, because it contains old id.

Example:

{
  "applinks": {
    "apps": [],
    "details": [
      {
        "appID": "{TEAM_ID}.{BUNDLE_ID}",
        "paths": [
          "*"
        ]
      }
    ]
  }
}

2. In case of firebase dynamic links, I had to change my Team ID in project settings. Then to make them update apple-app-site-association file for your links you have to contact support.

Reference:

It is cached, so can take some time. If you're still seeing it after a day, please file a ticket with Firebase support who can route it through to the Dynamic Links team: https://firebase.google.com/support/contact/?category=troubleshooting

UPD:

I've got response from support and everything is working, hope my answer helps someone!

Hi Abzal,

Andy here, and I noticed that you've recently updated your iOS app's Team ID. Once this is updated in the Firebase settings, it can take a few minutes for the AASA file to reflect the latest changes.

Please check this on your end if the AASA file is now up-to-date.
