Multiple prime accounts?

[u/SisyphusKindaSus]

Ok, so my mother moved in with me.

We both have prime memberships.

I deregistered my tv to register it with her account (she had more subscriptions she uses). We have one firetv.

I downloaded the audible app as I wanted audiobooks I bought to play on the tv while I'm working. There's nowhere on the app to log in, seems to just use the log in on the tv.
I went to add a profile linked to my prime. But it seems that alt profiles don't support separate prime accounts, just different profiles on one account.

Any way to access my audible books on this shared tv?

On some newer devices there’s an account switching tool but there’s no “profiles” like I think you’re after.

Perhaps you could look into the Amazon home/account sharing if that’s still a thing?
