Marketplace Central
Marketplace Central is a web application that may experience typical issues from users around login issues or page loading (especially updates). Additionally, during the initial 24hrs after installation, the application may be awaiting data population from your existing AWS Marketplace account.
If users are having issues with their initial logging in, it could be an issue with the Cognito temporary password. It is common that the remedy is to delete the users from the Cognito User Pool and Re-Create them in the Marketplace Central Configuration.
