Hello again
Since Virtuemart 3.4.0, I've noticed that products are auto removed from the cart when I choose an address field which triggers AJAX loading. I'm running
Virtuemart 3.4.0 (same problem with 3.4.1)
Joomla 3.8.12
PHP 7.1.22
VirtueMart Core does not have Ajax Auto Reloading for address fields.
Are you using a third party checkout?
Regards
Stefan
