Understanding Data Streams In Google Analytics 4 (Everything You Need To Know) 

Thank you for this great content!! Very useful! I have a doubt I hope you could help me.: I really need to find a way to collect the data stream app (ga4 account #1) to use in (ga4 account #2) without alter any condition or setup, just access the data. If I am not mistaken, there is a possibility to transfer/move the property that contains the data stream app to the new account, but my boss said to don't change any previous configuration. I just want to get the data, so I can use the Rollup reports in ga4. I have the admin access for both accounts. I did my research and, the only answer came from ChatGPT, after dozens of videos on youtube. - - - - Yes, it is possible to connect the tracking data stream (app) from one GA4 account to another GA4 account without losing historic data. Here are the steps to do so: 1. First, make sure that you have admin access to both GA4 accounts. (OK) 2. In the original GA4 account, go to the "Data Streams" section and select the app data stream that you want to transfer. (OK) 3. Click on the "Settings" button for that data stream and select "Measurement Protocol API." (OK) 4. Copy the Measurement Protocol API Secret and Measurement ID. (OK) 5. In the new GA4 account, go to the "Data Streams" section and click on the "Add Stream" button. (OK) 6. Select "Mobile app" as the stream type and follow the prompts to set up the new data stream. (OK) 7. Once the new data stream is set up, go to the "Settings" section for that stream and select "Measurement Protocol API." (HERE.. I DIDN'T FIND IT) 8. Paste the Measurement Protocol API Secret and Measurement ID that you copied from the original GA4 account. 9. Save the changes and wait for data to start flowing into the new GA4 account. - - - - - - Can anyone help and tell me if this answer is correct or if it is just a common error of chatgpt answers? Thank you in advance!!

HOw do I view the analytics of this new stream. I've added a subdomain to my streams but don't know where the analytics are

Are you supposed to create separate accounts for websites or create new streams for websites in one account? How do you view analytics for one stream if you have multiple streams?
