I have try to place order using Authorizenet payment method (Test Mode) but every time I can not go to success page. No any error occur but all the script executed and after loader continue loading not going to success page and in the background order successfully placed. When I have go to success page using url it will showing Order successfully placed.
I have checked all the magento 2 versions including latest version 2.1.2.
Can you please check and resolve it.
If I understand you correctly, the transaction appears to be successful but you don't see the success page in Magento?
If you login to the merchant interface, is the transacting listed there? Do you receive a successful transaction email notification?
