Hi @Pham, Andy,
Thank you for reaching out to Microsoft Q&A forum!
The LUIS is being phased out and new LUIS Authoring resources can no longer be created after April 1, 2023, you won’t see the option to create a new Authoring resource. Instead, consider using the Azure AI Language service, which includes similar language understanding capabilities. If you need to manage existing LUIS resources, ensure you’re using the correct subscription and accessing any pre-existing resources.
LUIS will be retired on October 1st 2025 and starting April 1st 2023 you will not be able to create new LUIS resources. We recommend migrating your LUIS applications to conversational language understanding to benefit from continued product support and multilingual capabilities.
I hope you understand! Thank you.
