My son has an Apple Watch SE 3 and it doesn't feature the keyboard and you literally cannot type a lower case 'n'. The only hack was putting in a space and then it will sometimes do an n (or multiple characters). It's bonkers bad.

The apple watch has a kind of small space for writing letters, and underneath, a long “space” key. The character recognition is somewhat not optimal.
