Action Required Switch to the Play Referrer API by March 1, 2020

I checked with Firebase support for this, as I can see firebase libraries are using install_referrer. Got below response from them:

This is a great catch. Thanks for bringing this to our attention. I'm currently in discussion with our Analytics experts and will get back within 48 hours, or as soon as I have more information. For now, no need for any action from your end, wait for the next update from the Firebase team.

I think we should wait for the next update for firebase libraries, they might fix it. We have the deadline of March 1st, 2020. I think it is enough for the firebase team to update the libraries.

If you have used this API in your code by yourself, then you need to change it immediately as you are not depending on firebase or any other third party library provider.
