I am not sure what kind of problem this is, but when I use the QR code on the Crowdsale page and if I do a buy function from my mobile wallet, the transaction fails. I thought that buying direct from the Crowdsale contract address would work in a ICO stage.
aka CrowdsaleInfo address is: 0x156504bC8F49cf34E0f275b47557b739eBB0A8d7
This is on mainnet
I can’t finish my wallet and buy sell system before this is working.
