The change means the document was added to your file and the case is ready for review by a Consular Officer (there is actually no time frame for that), but hopefully it will not take that long.
We are in the same boat, our case shows Ready, my wife had her interview more than a month ago and she was asked to provide additional documents.
The date was updated to date when they received the documents (23-May-2022) with a status of Ready.
No further action since then and we are still waiting
(They kept my wife's passport)
