The Reddit user said that Coinbase made a serious error in the implementation of SegWit, without updating the protocol BIP70 to support SegWit-addresses. When paying for merchant services through the coinbase.com gateway, they will not receive the funds, because they will be lost due to incompatibility with SegWit-addresses, and as the company does not have merchant support services, no one will solve the problem. Well, what can I say: this is Coinbase, we wait (most likely for quite some time) fixation.
