thanks. I found the transaction in Blockchair by putting the legacy BTC adress to where I sent these BCH. However I don't know how to recover my ledger BCH wallet ? I have the private key of course as it is all mine (BTC adress and BCH adress on my ledger nano)

I've already checked this topic on the ledger support and tried it, but can't find any BCH in main BCH ledger wallet ?

Hello, I've sent BCH (from Kraken) to a BTC legacy address in my ledger wallet, can't find these BCH ? the trabsaction is confirmed and exist in the blockchain.
