Single Wallet on Trezor, multiple accounts (SegWit, then Taproot).

Tried adding m/44'/0'/1' (or M/44H/0H/1H on Coinomi) and m/44'/0'/1' without luck.  BlueWallet details says it at m/44'/0'/0'

Back on the x vs z pubs.  On Trezor, when I show the "xpub" to scan, the typed version starts with "tr([db373be9/86'/0'/0']xpub........../<0;1>/*)"  tr presumably means taproot, no idea what the db###be# stands for, then it has the 86' derivation path start.  It's so weird that BlueWallet would show it as an m/44' unless it translated it into something different.

trying on Electrum now...
