*Scam Alert* the bad connection issues aren't just annoying. I had a transaction submit twice due to their apps connection problems. I was charged 2x for one successful transaction. Contacted support immediately. Their advice was to sell. This is obviously profitable for Coinbase and a loss for me. Coinbase profits off their own "mistakes." They will reply to this review asking me to contact support. Make no mistake, COINBASE HAS NO FUNCTIONAL SUPPORT!
