After restoring the wallet in Daedalus Flight wallet, the recent transaction history in Mainnet Daedalus wallet disappeared.
This is caused by an address format change, the transactions actually happened, but are not showing in the UI.
When we release a new version of Mainnet Daedalus based on Daedalus Flight, this issue will be resolved.
If you continue to experience an issue, please be patient and remember that our support team is here to assist.
To submit a ticket to IOHK support, you can do so from the Help menu in Daedalus.
