How to get a Tracking_ID in Google Analytics for iOS apps for Google Tag Manager usage?

Question

I've set up my account in Google Analytics, Google Tag Manager and have already installed firebase/analytics and GoogleTagManager to my project...

The problem is when I go the admin section and click on the default property created for my app I have no Tracking_ID on property settings menu, the property is set as app + web I've tried to set a new property as App it then gives me only a .plist and no Tracking_ID for managing the events on Google Tag Manager...

Is google tag manager a tool meant to be used only for web now? Because I installed it on iOS but it seems GA doesn't provide Tracking_ID for mobile tracking and without Tracking_ID I just can't use GTM...

Any help on this matter would be highly appreciated, Thank you all in advance)

GA App properties were sunsetted and are now app+web properties.

In GA for the Property you created, you also need to add a data stream. App+Web Properties use a Measurement ID, not a Tracking ID.

When you add an app data stream, Analytics creates a corresponding Firebase project and app data stream, and automatically links the Firebase project to your property if your project and property are not already linked. Currently, you cannot link to an existing Firebase project from Analytics.

Enter the iOS bundle ID or Android package name, the app name, and for iOS, the App Store ID, then click Register app.

Analytics will progress through the steps of creating a Google Cloud project, a Firebase project, linking the Firebase project to Analytics, and creating the app stream. Click Next.

Follow the instructions to download the config file for your app. Click Next.

Follow the instructions to add the Firebase SDK to your app. Click Next.

Run your app to verify installation of the SDK and that the app is communicating with Google servers. Click Finish.

Alternatively, click Skip this step if you want to complete app setup at a later time. Click Next.

GTM also has two new tags in it - GA App+Web Configuration tag & GA App+Web Event.
