Hello Nghia Huynh,
Welcome to the Microsoft Q&A and thank you for posting your questions here.
I understand that you are getting failed to update application error: No other properties may be modified when certification properties are being modified.
This is a common issue when trying to update your app manifest. The error message "No other properties may be modified when certification properties are being modified" typically means that you cannot change any other properties while the app is undergoing certification - https://techcommunity.microsoft.com/discussions/teamsdeveloper/cant-update-the-app-registration-for-my-teams-app/3997383
This is a similar answer to your question by @LETLHOGONOLO MOSENEKE via https://learn.microsoft.com/en-us/answers/questions/1366566/getting-error-when-changing-accesstokenacceptedver
You can take the steps below to resolve this issue:
- Make sure that your app is not currently in the certification process. If it is, you will need to wait until the certification is complete before making other changes.
- If you need to update certification-related properties, make sure you are only modifying those properties and not any others.
- Sometimes, using the Microsoft Teams Developer Portal instead of the Azure portal can help. You can directly update the manifest in the Teams Developer Portal without encountering this error.
- If you need to update both certification and non-certification properties, try separating these updates. First, complete the certification-related updates, and once they are processed, proceed with the other updates.
I hope this is helpful! Do not hesitate to let me know if you have any other questions.
