We recommend waiting ~ 10 minutes and checking again. All transactions have to be verified by the Abra system.
However, due to congestion on the blockchain it may take longer to reflect your deposit.
Additionally, if you have multiple wallets, you will not see the balance of one wallet on another. Each wallet is separate and will reflect the balance of that wallet only. When the Abra app is downloaded to a new device, or deleted and reinstalled on the same device, a new wallet and recovery phrase is created. Each wallet has its own specific recovery phrase which is NON- TRANSFERABLE.
