It's not. Trezor (any hardware wallet) only shares the xpub (master public key) with Electrum. No private keys are ever shared, that's the point of using a hardware wallet.
Yeah exactly.. so just wondering why Electrum wouldn't see the addresses I rescanned as being unspent. Thought maybe there was something I was missing. Its like they're stuck in watch only mode or something?
Yeah Electrum Personal Server. Everything looks like its communicating fine, just not showing a balance. I haven't tried connecting to another server, maybe thats next if this final rescan doesn't help
