Please help. I sent BTC from Armory .96.5
It was sent from a Legacy address to a BC1 native segwit address. It was successfully received, but the transaction still says unconfirmed in Armory, so I can't spend the remaining balance.
Can you make this thing clear you mean that you received the BTC successfully in your Segwit address and confirmed but in the Armory wallet it stays unconfirmed?
If the transaction is confirmed on any block explorer but unconfirmed in the Armory wallet it means the Armory wallet is not syncing properly with the Bitcoin node or the Bitcoin core is not syncing properly to download the latest block that includes this confirmed transaction.
A possible cause of this might be the current HDD/SSD space is low.
If not then maybe it's just a system issue you can try to shutdown the Armory and bitcoin core restart the PC and open bitcoin core again and check the transaction again lets see it would sync properly with the updated data from the blockchain.
