There is a "Multiple Private Keys" section where you can see that information
There is section like you said, but it is only written YES or NO, so we don't know exact numbers of seeds that can be stored devices, or at least I couldn't find that information.
Most HW wallets are pure crap
I never said that most hardware wallets are crap, and majority of discontinued devices that are now useless are mostly coming from ledger and coldcard, that are not even open source.
Hardware wallets should work more on adding encrypted backups, that are much more important for keeping backup safe and well protected.
