I have never had any problems sending anything using Segwit BUT it now seems my new Nano S Plus only supports Native Segwit and Taproot.
I don't own any Ledger devices, but it appears that they're still supporting older address formats: How to add different formats of Bitcoin accounts in Ledger LiveI have sent a transaction from my old BTC Segwit to my new Native Segwit and it appeared virtually instantly even though it still shows as unconfirmed on Mempool?
It'd take roughly 10 minutes for each confirmation [assuming that you used an appropriate fee and there's no stress on the network].Do I need to switch all BTC to Native Segwit?
If you're not planning to use a super outdated software or platform [compatibility issues, but it's super rare nowadays], you should make the switch [you'll also benefit from its lower transaction fees].- If I were you, I'd worry more about their recovery tool: Ledger Recovery - Send your (encrypted) recovery phrase to 3rd parties entities
