Greetings!
I’m guessing from what I am reading that the menu was fine until you did the updates?
I just went to your site on my phone and tablet, and the menu appears to be working on my end. I tap it and it drops down the menu links and I can navigate. Is working for you now?
Thinking things through, I thought maybe the problem was in the JavaScript.
I changed the JavaScript minifier from Google Closure Compiler to JSMin.
It’s working fine on our two windows desktops, in Safari on the iPhone, but not working in Chrome on the Android – which is the biggest share of my traffic.
hmmm…not sure what to suggest because I don’t have an android phone. Perhaps it’s the fact the script is getting minified could be the issue. Try it without minified scripts, and make sure it’s not a plugin that combines scripts as some do.
