I use Magento 2.3.3 and the module v1.1.3. I see that after installing the module, the order sale grid slower.
Do you have any workaround to improve the speed?
1. The cause:
The order grid loading slow due to the module calls repeatedly orders and each time loading and update all the grid.
Here is the quick workaround for improving the speed of the order grid during waiting for our update.
Please disable refund status column at Sales => Order
Look for the file <magento_root>/app/code/Bss/RefundRequest/view/adminhtml/ui_component/sales_order_grid.xml
remove or renamed it to sales_order_grid_disable.xml
Flush the Cache and the error will disappear.
If you need any further assistance, please feel free to contact us via email email@example.com
We'd be happy to help you out.
