Dear Sir or Madam,

We would like to apologize for the issues currently affecting TUMvCard and TUMcourses.

Due to the required API migration by Campusonline described above, isolated errors are currently occurring in the display and functionality of the affected services. We understand that this may cause inconvenience, and we sincerely regret any disruption this has caused.

Most of the affected errors can be corrected manually on our end, allowing your website to function as usual again. If you experience any display issues, please do not hesitate to contact us. In parallel, we have already reported the issue to the responsible Campusonline team to ensure that a sustainable long-term solution can be implemented.

We hope for a prompt resolution of the underlying cause and would like to thank you for your understanding and patience.

Kind regards,

Your TYPO3 Team
