Redirect subdomain to another site not working

I recently migrated a site from https://dreamcatcher.alejandraleon.com to https://dreamcatcheroracle.com. The Netlify accounts are dreamcatcher.netlify.app and alejandraleon.netlify.app. Both sites are hosted on Netlify with DNS management.

I have setup the following redirect on the alejandraleon site which is not working:
https://dreamcatcher.alejandraleon.com/* https://dreamcatcheroracle.com:splat 301!

I have confirmed that the _redirect file is working for other redirects, so it’s something specific to redirecting the subdomain. I also tried without the https added but it also didn’t work. Thanks for the help!

Just figured this out… by creating a Domain Alias here: Netlify App the redirect now fires for the subdomain.
