The cause of an “UNSUBMIT” transaction, might be one of two:
- Bad network connection
- The Ethereum network is clocked by a high number of transactions.
How to resolve and successfully submit the transaction:
- Check if the mobile phone network is smooth and try to switch your network to WiFi or 4G
- Find the corresponding transaction on the “Transaction History” page, and click “Resubmit”
After the transaction is successful, the status will update to “Pending”
