Faced a problem. I bought NFT and gave the seller the old wallet address. The address at the time of purchase has changed several times. After reinstalling the wallet on another computer and restoring the Sid phrase in the wallet, there is neither a chia balance nor all the NFTs that I bought to the old address.
Close Chia app
Delete wallet database file (not full node!)
Restart chia.
Wallet db: /user/.chia/mainnet/wallet/db
Next version of chia will have a resync button. But for now above will fix most wallet issues
