The protagonist problem with TPM isn’t really just “it has too many main characters,” it’s more that none of them are truly fleshed out in the way a protagonist should. To that end I’d say Rogue One has a similar problem. There it’s clear that Jyn is the one you’re supposed to hang your hat on (whereas TPM doesn’t really have that), but she’s not fully formed in the way she should, which does get it closer to the TPM problem (though, don’t get me wrong, I’d say Jyn is much better than Jinn).
