No, you do not have to do anything. Even if your points have not been transmitted for several days, they will not be lost and will be transmitted automatically at a later date.
If you see a note in your results list on My CME for more than 12 months that the points transfer did not work, there was a technical problem in the communication with the server of the German Medical Association that could not be resolved. In such a (very rare) exceptional case, you must prove your successful participation by manually submitting the certificate to the Medical Association.
