Depositing EOS to your Multi.io account requires both a deposit address and a deposit memo.
The deposit address generated for your account is identified by matching the ID in the Memo field. Without this Memo ID in your EOS deposit transactions, the system will not be able to credit the deposit to your EOS account.
EOS Deposits with a missing Memo ID or not included as is with no additional symbols/spaces will cause significant delays in crediting the transaction to your account.
If you made a deposit without the Memo ID please submit a support ticket.
