I installed the Amazon Sales Channel Extension and one of the steps in setting this up is to generate an API key in my Magento account per these instructions: https://docs.magento.com/user-guide/v2.3/sales-channels/asc/amazon-verify-api-key.html
When I try to generate an API key for the production environment from my Magento account, nothing happens. The page appears to be be broken. Every time I try generating the API key per the instructions and once hit “add new” nothing happens. I get no API key, just a blank
I'm able to generate a key for my sandbox environment without issue.
