My Ae coins are migrated. I’m using same device with AirGap Wallet and Vault.
I have tried several times. At my first attempts I got to the point where it showed that transaction is pending, and after many hours there was no transaction. Now, when trying to send, I get till the message “transaction broadcasted!”. After that nothing happens and no transaction.
I have the latest versions of Vault and Wallet. I’m using Android version 6.0.1 (2016-11-06). Device is Xiaomi Redmi 4
