I've sent this same issue in at least 10 times on both s5 and s8 over the last 12 months.
They never do anything about it. Screen shots sent too and they say you got your double rewards. It's bs. If you have a expo saved from previous day you get the double tokens but not the double gold. Not til you reset fresh. They don't understand that. You can explain it 10 different ways and show them the evidence and they still can tell with there own eyes the difference between double and single gold.
