After installing from playstore. The first step that I did is created new wallet address. Then I asked someone to send some amount bytes. He sent me bytes at my new address. Then I realized shouldn't make new address wallet.
I should used existing "small expenses wallet" instead of new address wallet.
Then I sent bytes from my own new wallet into my own "small expenses wallet". The amount bytes remain 599.452, after that I tried to chat at bot and copy my "small expenses wallet", there is nothing happened.
I think that is my fault didn't be careful to read guidance.

There was a mention of using a single address wallet, so maybe that was part of the problem? You have to use the address which was part of the referral maybe?

I think so, I didn't read it. Next I will try using refferal address. :)

I have already installed a new one wallet through your link mentioned above (I had uninstalled the old one because my wallet is not set up as single wallet).
Next step what should I do?
