Coalition App —Changing “Right to Waive” for Recommendation Letters

My son accidentally did not waive his right to view his letters of recommendation in the Coalition App. Once the letters are complete, the waiver cannot be edited. He has not yet submitted his application. Has anyone else ever done this and managed to fix the problem?

Does anyone know if it is possible to delete the contacts and then re-send the ”invitations”? His recommenders are aware of the problem and are happy to resubmit their letters.

We have sent the same question through the Coalition Help site, but the deadlines are fast approaching and we don’t know how long it will take for them to answer. Thanks.
