Balance zero after recovering wallet from seed-phrase
I ... downloaded BRD wallet ... then proceeded to recover wallet ... but [it] brought up my account with zero funds in it.



Choose Sync Blockchain (Menu > Settings > Sync Blockchain). 
Wait five hours
Check balance


If not try


Uninstall Bread Bitcoin Wallet.
Reinstall Bread Bitcoin Wallet.
Bread will ask you to type in your 12-word key in order to re-instate your Bread Wallet.
Now your balance should show as $0.00. This is normal.
Sync Blockchain (Menu > Settings > Sync Blockchain). Note: takes several hours.
Bitcoin balance should now be displayed properly.
