Hi, i know what your problem is and i will post the guide here on how to recover the coins, if you agree to leave a tip after you've claimed it?
did you just create a new bitcointalk account for posting reply in this thread?

---snip---
It seems that the ledger does not recognise the BTC Segwit Address it gave me for whatever reason.
---snip---
Since then I have learnt that the ledgers xpub does not match the BTC Segwit Address but it does the BCH & LTC - so how is this possible?
Is there a way on your ledger to turn on/off segwit address usage?
HCP has told you how to use iancoleman tool by using xpub in the old thread
post #8but please try again this time with the 24 word seed you have
- paste your 24 word seed into
"BIP39 Mnemonic" input text, and make sure
BTC is selected
- on
"Derivation Path", click
"BIP49" and check the addresses
- try a few times with alternate combinations
"Account" 0 or
1 and
"External/Internal" 0 or
1- if with all 4 combinations you still cannot find the address, try BIP141
- go back to
"Derivation Path" and click
"BIP141", make sure
"Script Semantics" is
P2WPKH nested in P2SH- try different
"BIP32 Derivation Path" (above "Script Semantics") with
m/0 and
m/1- if you still cannot find the address, keep fiddling this tool with any possible derivation path you can think of
your address must be generated somehow from the seed with certain derivation path
