Hi @karzin
Thank you for your help.
I updated the plugin and followed like you said. It is getting more consistent but still not working as expected.
I noticed something that might help: If the user visits the site without the coupon parameter, but then visits the site with the coupon parameter, the coupon will load once items are added to the basket.
If the user just visits the site with the coupon as the parameter, it will not load the coupon automatically when items are added to the basket.
Thank you again.
All the best,
Jay
