For our app, we create envelopes with a document for signing for DocuSign’s eSignature app using the DocuSign Api. Everything was fine until Q1/Q2 2024. Now, customers report that they no longer can edit/delete documents as described here
https://support.docusign.com/s/document-item?language=en_US&rsc_301&bundleId=gbo1643332197980&topicId=fjx1578456267870.html&_LANG=enus

Envelope is in state created at this point.

When manually uploading a doc, I still can use the feature described above. DocuSign support could not help. Any ideas what might be the problem here?
