After configuring Google Analytics today I now have an issue with submitting an order on mobile devices.
If I select a shipping method and submit the order I get a warning that the shipping method is missing. When I check, it has definitely been selected and if I try to change to a different choice I still get the error on submission.
If I then go and disable Google Analytics and reset the cart it then works successfully. Upon re-enabling analytics it fails again.
It seems to only be on mobile devices, desktop is working ok regardless. I have tested on my mobile using chrome, android browser and firefox with same results and on different connections.
No idea where to go with this one, can someone help?
