Twenty Sixteen Mobile Menu Button not working

Has anyone else experienced this issue on twenty sixteen?

Hello cse16, well I am a novice myself and just wanted to ask if you ran a Google Page Insights test after you built your sight? It will give you a score and errors that you might have. I myself had to learn a lot of things three years ago and even more since 4.7 wreaked havoc around the world
There are more than one tool available for mobility tests. I just built three Theme 2016 sites only to be crashed by 3 hosting companies due to various reasons, maybe a plugin is causing a conflict.
That is a good thing and a bad thing about WordPress, using any of their themes because they are primarily designed for blogging and to build a website using one can be a challenge.
I have never been able to get help with my issues because what works for one does not work for all, and you can read all of the posts on Theme 2016 and if you are not a WordPress expert then it makes it difficult. Like myself I taught myself WP and used theme 2013 3 years ago and it was not easy but it worked fine until 4.7 came out, then I had to start all over again and I chose Theme 2016 but I had to learn some css in order to accomplish my goal.

Thanks Larry, for your thoughts. I have run a couple different analytics-type tests (onpage.org, google analytics), and I know there are a lot of problems that should be fixed/improved. I intend to work on them as I have time/learn more about it.

My main concern for the moment is how to get the menu button to expand correctly when showing on a mobile screen. I may have to admit defeat and go to a different theme entirely.

What do you think?

I’m running WordPress 4.7.2, Theme Twenty Sixteen.
