Approvals Not updating

I'm having a problem when retrieving the approvals created. Until 2024-12-26 at 13:16:48 UTC, when I created an approval, either through the application or through the API, it immediately appeared when I used get in the endpoint: https://graph.microsoft.com/beta/solutions/approval/approvalItems. Now I'm only able to see the approvals from before 2024-12-26 at 13:16:48 UTC, there is no record of the new approvals.
I also noticed that, in the application, it's not showing the name of the person to whom the approval request was sent, only the name of the person who approved it, both for the new requests and for the old requests that have already been completed.
