This plugin no longer functions as intended. It was not easy adding my niche (Pillows) products but I managed to manually select and add them to my website shop. The products all disappeared from my website recently without notice and it is due to the plugin. So much hard work of importing products and editing the Titles and details; it's all gone. This is very frustrating and disappointing. From all the negative comments and reviews recently from others, it looks like I am not the only one having major issues with this plugin and it's evident a new plugin needs to be considered because I cannot even add new API keys from Amazon. It is saying they are invalid. The previous keys were invalid (once valid) and I thought I only needed to add new keys. Nothing seems to be correcting the issue and so I had to put my website in Maintenance mode until I can rebuild it. If anyone knows a solution, hopefully it can get posted here.
