I collected 15 BAT on my mobile phone , because it was the minimum in order to sync with the wallet, but when I did the sync it appeared only the BAT from my computer (10 BAT), this happened a week ago
Thanks for reaching out. Unfortunately, the bat is not synchronized through sync only through the wallet, if you would like to manage you bat on your mobile device please connect your wallet account to your mobile device . If you have any more questions please let us know.
Thanks for your understanding and have a nice day!
