Azure unable to generate TXT hostname record.

**Describe the bug**
I used static web app to create my website(blog) using my github repository and all went well. During the process of adding custom domain from hostinger a DNS provider, I had to generate the TXT record so I could add it in my DNS provider. After clicking generate code it generated the code but the status of that record is still showing validating and is buffering for hours. Also I am unable to delete that request.

A clear and concise description of what the bug is.

**To Reproduce**
Steps to reproduce the behavior:
1. Create a static web app resource, I used the free trial subscription, and free hosting plan for this.
2. Used my github repository to add source file.
3. Finally the deployment was successful.
4. Inside the custom domain panel, I clicked the button the create a custom domain on other DNS.
5. Input the domain, I entered 'www.gaisensei.com'
6. Then selected the TXT to generate the record and add it to my DNS but when I clicked the generate code, it did generate the code, but the status keeps showing me validating and is buffering for hours.
7. I even tried to add the same record in my DNS provider but it's showing error of wrong record input.
8. I chose TXT as type, www as hostname and the generated code as value in my DNS provider and it's showing error with this. In Azure it's show www as hostname.
9. Same problem occurs when I created a new request and this time I choose the CNAME first and pasted information that appeared in my DNS and still the it shows the wrong record input warning.
10. Well I was not able to delete my request for adding new custom domain, when I selected the TXT and clicked generated code button.
