@jfversluis , do you think you could ping someone with write access to review this PR? Thanks!

@salvadorjesus that is me but I didn't merge this because it is unfortunately unlikely that we will actually do a release with this change in it since the end of support is May 1, 2024.

In fact, maybe to not give the wrong signal about that, I will close this one.

If this is something you need, please consider moving to .NET MAUI or if you need this for Xamarin, implement this functionality in your own app or fork this project.

Thank you @jfversluis and @jsuarezruiz.

We are porting our app to Maui, but we're still months away. I know for a fact that there are many teams in our situation.

I'm leaving here the Azure devops link for this PR so anyone who needs this can reach this easily.

Regards.
