include firebase dynamic links for iOS in react-native

i try to include dynamic links in my react-native application

i installed @react-native-firebase/dynamic-links and listening in the app for open links

dynamicLinks().onLink(link => {  this.handleLink(link);});dynamicLinks()  .getInitialLink()  .then(link => {    this.handleLink(link);});

for android i included the scheme in the manifest as follwed and everything works fine

<data android:scheme="app" android:host="appname"/><data android:scheme="https" android:host="link.appname.de"/>

I added 2 dynamic links in firebase

• https://link.appname.de (i own the domain)
• https://appname.page.link

after that i did the following steps for iOS(from this page https://www.codingular.com/2020/01/deep-linking-in-react-native-using-firebase-dynamic-links/)

• uploaded the apple-app-site-association to my webspace appname.de
• added a URL Type in xcode with Identifier: appname and url schemes: "bundleID"
• added the associated domain applinks:link.appname.de & applinks:mymories.page.link

finally added the FirebaseDynamicLinksCustomDomains key with https://link.appname.de to my info.plist

but after all my app is still not opening if i click an a provided link. In android everything is working fine.It just shows me an error page in the browser

Requested URL must be parsable and complete DynamicLink

Would be nice if someone has a hint for me or explain me what i'm missing
