I've got shared orders in my amasty.com account, how do I move them to projects?
Due to optimizing module download and registration processes, we have deprecated the old order sharing feature, and it is planned to be fully shut down in the future. If alternative configuration isn't arranged, this will result in losing access to downloading shared extensions. Therefore, if you shared any extension orders with other amasty.com accounts in the past, or if someone else shared such orders with your account, we recommend switching from order sharing to project sharing at earliest convenience. This switch will allow to correctly access and register the extensions, as well as download them via Composer.

In Composer, access to extension packages in shared projects is granted on the
project level. Therefore, downloading added extensions is possible via Composer with the help of Composer keys from a specific project, not the account-level Composer keys from Products tab (that functionality is deprecated, and we recommend replacing account-level keys with project-level keys at earliest convenience). You can find more details about obtaining project-level Composer keys
in this article.
