This is useful as a reminder to make it easier for existing users to find your app.

Also, the marketing site being outside of reach of the app dev team is a real problem worth addressing with convenient snippets such as the linked solution.

That said, I'm still not convinced that an automatic redirect is a good idea.

I've had cases where I would like to refer someone to e.g. the pricing page (or a page I remember about a particular feature they need) on a SaaS marketing site, but had to open the marketing site in a new browser to find the link, because I keep getting redirected to the app while logged in. Someone else might have given up and the referral could have been less effective.

I propose rather updating navigation on your marketing site for logged-in users, making it easier to navigate to the app manually.

Yea I agree. For some reason marketing teams love to make the "log in" link tiny, if they include it at all.
