The GUI wallet doesn't give me an option to include a payment ID and Binance requires it. Possible settings like those in version 14 no longer show. How do I send XMR to Binance now? Thanks in advance.
Long, unencrypted payment IDs have been removed from Monero since v0.15. Only standard addresses, subaddresses and integrated addresses (which embed an encrypted payment ID), can be used now.
Binance have announced (2019/11/28) that they will be supporting the update and will be following up with further details when they reopen deposits and withdrawals for XMR.
