Please contact OpenLedger support. Open https://openledger.io/ , click the "support" link at the bottom. Others can't help you.

Hi all,
I processed a transaction to withdraw OPEN.BTC today using the OPENLEDGER. The Transaction is shown as complete in my BitShares Wallet Activity history, however the Block Explorer is showing no transaction for the used address.
How long should this take? Previous transactions have been confirmed at my receiving wallet within 10-15min. It's now been 90 minutes for this one.
Can anyone assist please?
Thanks
