Amazon Prime? - 1

Assuming I get Amazon Prime now, with Twitch Prime and all the trimmings, I can then apply for the Twitch Prime content on my Twitch account, like subscribing to a channel once a month, even if the Amazon account is on a different email -Address is addressed? For example, my Amazon account, on which I would get Prime, is "Max@mustermann.de". Can I then connect the Twitch Prime content with a Twitch account that is registered to the email address "Max2@mustermann2.de"?

You link the Twitch account with a Prime account, so give an authorization on the Amazon site. The email address does not have to be congruent.

It doesn't matter, it still works.
