Nunchuck doesn't seem to be working with the BTC Signet test network. I enabled the network on the app and sent signet test coins from a faucet. They never arrived. I used the desktop version of nunchuck with the same seed. No coins. I installed electrum using the same seed and the coins were there. I thought maybe the Nunchuck signet server was misbehaving so I tried using one of the electrum signet servers with Nunchuck. Same result. No coins in Nunchuck.
