Are you having issues with Litecoin address for sending/receiving?

If so then this might help you!

Litecoin changed its format for some of its addresses.

• "L" addresses are non-P2SH (non-SegWit) addresses and they remain unchanged (Legacy Litecoin accounts)
• All addresses starting with “3” will now begin with “M”. (Note: The entire address changes)
  
  This will not affect your litecoin holdings/amount.
  3 and M addresses are freely convertible.

What is the benefit of M addresses over 3 addresses?

Benefit is that you cannot accidentally send Litecoins to a Bitcoin address anymore, and vice versa,

which means you won't lose your coins 👍

Example Litecoins to your TREZOR? M-address refused?

Use a 3 address. Use the converter above to translate between them as TREZOR Wallet only accepts M addresses as valid P2SH addresses.
