Updated to AtomicDex 0.2.0 and Rick and Morty balances did not transfer. How do I retrieve these and will this happen with other coins as well.

Hello! 

Could you please ensure that you see same address as you've seen before the update? What about RICK/MORTY trasnsactions in transactions history?

Thats indeed strange situation because RICK and MORTY transactions are on blockchain so it can't be reverted and same seed is always produce the same address. Moreover, after app update previous wallet login information should have stayed.

did you use your password to login or use your seed words to restore your wallet?
