Hey. I had BTC in blockchain.info when the fork occurred. I had a small amount in my wallet and the larger amount in an imported address.

By using Coinomi I was able to get the smaller amount of BCH.

I have also used a service to receive my non compressed key connected to the imported address. When I use this key to "sweep wallet" in Coinomi I'm sent to a white page, then sent back to my wallet with small amount. (as compared with when I try the wrong key it says the address doesn't have any coins.) I have successfully used the same key to connect the address to Mycelium.

The imported address was also used to send BTC on Aug 8 and receive on Aug 10 if that matters.

What to do next? Thanks.
