Hi! I have the same issue. Tested in Safari 12.1 and Chrome 79 (looks like it happens with old browsers) in macOS Mojave and Windows 10.
“Uncaught SyntaxError: Unexpected token ‘.’ yith-wcan-shortcodes.min.js:1”
The error is in the assets/js/yith-wcan-shortcodes.min,js file.
Can you please check if it can be quickly fixed? Because I have to turn off Autoptimize for the site to work. Add some condition to support old browsers maybe?
