By the way, these are examples of callout extensions if you are not familiar with them. Sitelinks and phone numbers are just two options. There is also structured data, price extensions, call extensions, review extensions, and more.
Life is funny sometimes!
After I posted my update talking about how long this was taking, I checked my email and my publisher had sent me their edited version of my manuscript! Whoo Hoo!
I have spent the rest of the day going over their changes for approval and indicating any corrections I'd like made.
That is all done now and I'm so excited! The next step is the typesetting phase. They say it could take a month before it is sent to me for my approval.
Hopefully, I can be patient waiting for the typesetting to be done, lol!
