@Lucius - thank you

Yes, I'm taking my time, probably being overly cautious/paranoid, before I send my BTC to my Nano. I've scanned my PC with several different anti-virus, anti-malware, anti-keylogger, anti-rootkit applications, and made sure it's as clean as can be. I also use the On-Screen-Keyboard when working in Electrum and Ledger Live, as I've read that keylogger apps can't read this and can only read physical keyboard inputs. But I digress.

Thanks for the link on how to split BSV from BCH. I'm reluctant to introduce yet another wallet into the mix, as I haven't used Coinomi in the past.

I've sent off a support request to Ledger directly, asking for their input on splitting BCH from BTC, and BSV from BCH, and mentioned the article from 2017 which talks about how to do it in Ledger apps, which, btw, is here (but I think it's outdated, as it refers to Ledger applications which no longer exist, and have all been replaced by Ledger Live): https://coinsutra.com/bitcoin-cash-ledger-wallet/

I'll report back once I've made some progress, or when I hear back from Ledger Support.

I guess I'll figure it all out in the end, wish me luck!
