After bombing on the other tutorial (tut) I posted about, I tried this one.
https://www.tothenew.com/blog/aem-with-nextjs-remotespa-a-comprehensive-integration-guide/
In summary, the tut recommends the following
Use the archetype flag frontendModule=decoupled
Set the root page (us/en/home) template to spa-next-remote-page
As a result, the root page properties did not show me an SPA tab, as the tut had led me to expect
Why did this happen? Thoughts?
I will say, a lot of issues result from a mismatch between the archetype version and the AEM version. I am using A50 with AEM cloud from Sept 2023.
