Thanks for your reply.
I was just a little worried because it mentioned 'instability' of their Ethereum nodes.
How will you know it will arrive normally though? I'm wondering because of their 'important notice'.
Thanks.

As users are concluding that it didn't go through, another transaction is signed, and finally both gets transmitted, resulting in spending double the amount."
It's mainly recommended to use MEW if you want to spend your coins since Ledger transactions "are being broadcasted in double". But to receive, there should be no problems as only Ledger's nodes are having issues. This means that coins should arrive normally in your address as Ledger is only a "client" to control your coins stored in the Ethereum blockchain. The only possible issue is that Ledger doesn't see your incoming transaction. If this happens, you can use MEW to see and spend the coins or wait until Ledger fixes their nodes. But the coins won't be lost.
