I see it's been mentioned a few times, but yes, I have the same (it's been like it for a while)
Fresh machine, no cache, same problem.
Chrome console returns:
Uncaught TypeError: jQuery is not a function
at Object.hideLoading (common.js:123)
at Object.showLoading (common.js:93)
at HTMLFormElement.<anonymous> (common.js:717)
at HTMLBodyElement.dispatch (jquery.js?ver=1.12.4-wp:3)
at HTMLBodyElement.r.handle (jquery.js?ver=1.12.4-wp:3)
Can you try again now?
(make sure cache is cleared).
Ok this is a test from my mobile
I'm assuming the issue is resolved?.
After some thurrow testing with normal user it appeared to be a jquery issue with wordpress which has now been added to the theme functions.
This fixed the issue for my test user (and should resolve the issue for everyone).
Here is your desktop test to confirm 🙂
Good job!
