We plan to deprecate and remove the Credentials service UI, replacing it with an MFE. We had hoped to have the MFE ready in time for Olive, but it will not quite be ready for 1:1 parity. We will attempt to include the MFE in the Olive release though if anyone wants to try it out.
Please read https://github.com/openedx/credentials/issues/1722 for more information and to post any questions/comments. The proposed deadline for comments before acceptance is 25 Sept 2022.
