Under site collection A I have created a Master file and need to move the file to site collection B. After I downloaded the Master file, in site collection B > site settings > Master pages and page layout, I uploaded the file, publish it and approved it. Then I apply the Master to site collection B.
Everything looks fine. However when I open site collection B with SP Designer 2013, click "Master Pages", I cannot see my new Master file. I can find the file via All Files > _catalogs > masterpage.
I am not comfortable with it. Did I miss some configuration or it is a software bug?
P.S. I need to write a deployment guide to IT supports which do not have Sharepoint experience. Hence I want to make sure I am working in the "best practice" way. Thank you.
