Hi, @Rafaelebl, are you a Creator?
There is a known issue with BAT not porting to Uphold. Support is working on a fix and you can follow their thread for any updates to this issue:
You can try to see if the fix works for you: make sure your browser is the latest version v1.22.71, then disconnect and reconnect your Uphold wallet, BAT should drain directly from your browser wallet to your Uphold wallet. This fix doesn’t work for all, but there’s no harm in trying
