Advice on PWA on a separate mobile subdomain

Hi,

I need your advice. I have a client who has deployed a separate mobile subdomain with PWA, so they have

xxx.com for desktop

m.xxx.com for mobile (with PWA)

I guess they have to follow Google guidelines:

​

• On the html code of each mobile URL, it must exists a rel="canonical" tag, pointing to its equivalent URL on desktop version.
• On the html code of each desktop URL it must exists a rel="alternate" tag, pointing to its equivalent URL on mobile version.

Am I right?

Besides this, they have different titles and descriptions on both versions, I guess they have to make them the same.

Best Regards
