I cant get amp version of home and blog page at the same time

I′m trying to get amp for my homepage, blog page and post. Amp for post is running perfect. But is impossible to get amp for home and blog page at the same time.

My settings are:

– AMP on Pages: on (hide by default)
– Homepage Support: off

With this settings, amp in homepage is ok but(1):
– Blog page is non-amp if “Show amp for current page”=show (yes, show)
– Blog page shows the amp homepage if “Show amp for current page”=hide (yes, hide)

If I change settings to:
– AMP on Pages: on (hide by default)
– Homepage Support: on
– Front Page: off

the amp blog page is ok but the homepage shows the amp blog page.

If I change settings to:
– AMP on Pages: on (hide by default)
– Homepage Support: on
– Front Page: on
– Select Page as Front Page: my homepage

the problem is again (1).

Summing up, if I have my amp homepage ok, the amp blog page isn’t ok, if I have my amp blog page ok, my amp homepage isn’t ok.
