So can nobody help me with this? I also can't seem to work out how to send money from two addresses in one transaction. For example I want to send 1btc but only have 0.5 in two different addresses. Is this not possible now on the new blockchain.info? Used to be so simple. Not sure why they had to change everything.
I also haven't seen this feature in new wallet but you can try one option. Send bitcoin from your two address to bitcoin wallet address (there is one automatic transfer feature also but they don't calculate enough fee so transaction may get stucked for several hours). Better you send manually those bitcoin to your bitcoin wallet receiving address and than you can send it to any other address.
