I am trying to create my custom dynamic link: share.grabhotel.net of my custom domain : grabhotel.net. I follow these steps : Step 1: Add URL Prefix

Step 2 : Verify domain

I passed TXT value to my DNS like this

Step 3 : Add custom domain in Firebase Hosting

Step 4 : Add A records in DNS

But when I go back to my dynamic links, I get this error

Can you show me how to fix it ? And how to add custom dynamic link successfully ? Thank you very much
