My phone was stolen. I went to recover my bitcoins that were in my Blockchain.info wallet with my pass phrase. I recover the wallet but it doesn't contain any of the transactions of the last 7 months. I was told the pass phrase would recover all my coins! What happened?
Maybe you used an imported address or an old address thus it can't be found by the wallet software. Only the addresses generated using the new format (bip-39) can be discovered(are deterministic). Shortly said if you used legacy addresses the wallet won't discover them because they were not derived from a bip-39 master/wallet key.
