**Describe the problem:**  
All my cardano wallets no longer sync. Most likely due to the recent Chang hard fork will Koinly be updating?

**Which exchange/wallet is this regarding?**  
Cardano wallet address sync

**How did you import data into this wallet?**  
Autosync with wallet address

**What have you tried to fix this so far?**  
I’ve disabled autosync and reconnected
