Firebase upgraded properties are not yet supported in Google Analytics App

Recently I saw a message in Firebase Console to upgrade my Firebase property to Google Analytics property. Such properties are called Google Analytics App + Web properties in GA after upgrade. The primary benefit for upgrading the property that I see is that we can see all Firebase Analytics data in Google Analytics. Google Analytics is a tool that we all have used for years and it is slightly easier for me. I am also more comfortable doing analysis using Google Analytics than Firebase Analytics. On top of that we also get benefit of third party integrations like AdWords (now Google Ads) integration if we get all the data from Firebase Analytics into Google Analytics. So, I upgraded my Firebase property to Google Analytics property. The was a pleasant experience to see all Firebase Analytics data in Google Analytics in the format that I understand much better.

But soon I realized that there is one important part missing. On The Go, I use Google Analytics App to get a quick glance of my apps and websites. When I made this upgrade, I thought that I'll get all the Firebase stats in Google Analytics App as well. But Alas, I kept searching that property in Google Analytics App and not able to find. Later I realized that such upgraded properties are not yet supported in the App. Hmm, so I you are the Google Analytics App user, you will have to wait for some more time before you can see those properties in the App. There is no official communication about when can we Web + App properties in the Analytics App. Here is a small notification shown on Google Anlytics App + Web help page confirming the issue -
