This is a test post to see if I can get the Twenty Sixteen theme to show my post categories on the front page/home page and/or on single posts if I have at least one other post on my blog set to a different category (I currently only have one category used actively on my blog), at this time the Twenty Sixteen theme does not show categories for posts on the front page or single post pages if you are only using one category on your blog, which is annoying and unacceptable to exclude important post meta data like this in my opinion (I think that there should always be an option to show all the post meta data (authors, categories, tags, date, time-stamps, et cetera) on the front page and on single posts) regardless.
So this is a test post to see if I can get past this annoyance because the developers will not change this, I asked, but they intentionally designed the Twenty Sixteen theme this way for some strange unknown reasons; and so they will not change this.
I mean no disrespect to the developers, I just do not agree with your decision on this and on some other things, but I do want to thank you for considering some of my feedback and bug reports and for making the Twenty Sixteen theme and the previous default WordPress themes and for some of the other work that you do; and I hope that you will continue to make a default WordPress theme each year, and that you will continue to consider my feedback and bug reports.
If this works, then I will probably keep this post instead of deleting it so that my categories will show on the Twenty Sixteen theme and hopefully on other themes that are designed with this annoyance, but if this test does not work then I will delete this test post.
*This test was a success, and so I will be keeping this post for now so that categories will show on my blog when using the Twenty Sixteen theme and hopefully on other themes like this.*
