Hi. So the wallet address starts with a 1. When I initially set the nano up it did as you said, ask me if it was for legacy or segwit, there was an option for 'I dont know' which I selected as I didnt know. Now each time I go in I select the same 'I dont know'. I cannot find an option on the nano wallet app to find the address that it gave me to send to, to cross reference it to the one I used on coinbase, I am quite sure I did this correctly though as I checkes it several times forwards and backwards and gor mybhusband to do the same. Last night I sent a very small amount on bitcoin I had on my Jaxx wallet to the nano and although not confirmed yet, I can see the pending amount on the nano whereas the amount I am 'missing' only shows as pending on coinbase not on the nano. I know alot of you are saying be patient, which I am happy to do, I just want to know that I have not lost it. Time I can spare. £4.5k I cannot. Lol. Thank you all for your advise and please keep any suggestions coming as it is still not resolved.
