I have reinstalled Daedalus and the option of restoring Shelley wallet is disabled. What can I do to recover my wallet?
You say “reinstalled” but was this from scratch, an upgrade from a previous version, or a reinstall of the same version? And which version?
The solution was to simply wait for Daedalus to sync with the blockchain. A message would not hurt, informing the user that the Shelley recovery will be available after sync.
