Apparently, Google Maps no longer supports the previous syntax in IFrame that used to work.

I have tried with many addresses. They all work as is in the browser URL.

Also, if we go in Google Maps, manually enter the address, get the code from the embed function, the syntax is now encoded. So, we can no longer do it from the development environment. This was all generated from .NET. Now, from .NET, we cannot generate dynamic URL for the embed support.

Anyone knows what is going on?
