Mobile rewards has gone

Description of the issue:

I had 30+bat in my unverified wallet on android. I decided to verify it and link it to existing wallet from my laptop. I clicked that I already have a wallet, logged into it and my 30+ bat disappeared. Now I only see the amount I had in my wallet, the another 30+ BAT has’nt been added to the wallet balance.

How can this issue be reproduced?

  1. acquire some BAT in an unverified wallet
  2. Click the “verify” button (but do NOT click to create a new wallet/account with Uphold)
  3. Click that you already have an Uphold wallet and log into it.
  4. Notice the money you had before verifying is gone.

Expected result:

If you ask me if I already have a wallet, I expect that the money I have will go into the wallet I already have. I do not expect that my money will dissapear without warning and that my previously established wallet takes over my mobile without those BAT being added to it.
