HODL Totals in your Coinbase account can take up to 48 hours to update in COIN and the amount must be in the account for at least 24 hours to populate.
Please ensure the XYO balance you hold is in your actual Coinbase account and not your Coinbase Wallet or Coinbase Pro.
If you have any further issues after 24 hours have passed, please contact us by submitting a ticket here: support.coinapp.co
