Hi
Same issue for me, add to basket failed on production website after update to 3.0.7 but I discovered it after 3.0.8 update when a customer reported me the issue, it was working fine on some product categories and not on some other ones.
I had to rollback the plugin to 3.0.6 to have it working again and disabled the auto update
Can you please fix this issue?
Best Regards
