Ugh, I can so relate to this right now. I followed their Node embedded app tutorial closely, submitted my app, then found out they no longer allow embedded apps to use cookies like their tutorial does. Finding up to date documentation is a struggle and some of the components they suggest you use are closed source and completely undocumented.

I had previously built a rails app using Shopify CLI and it failed review due to some endless cookies loop that I could not reproduce caused by their gem. In the end, I just rolled my own OAuth / user database / Billing - but talk about a waste of time.
