Yes the dev Misovan is very helpful and responsive. He really want to improve the app anf fixing quickly all issues. But is normal for a new app and also using a new protocol to have various issues. Important is to give the dev all the feedback you can.

I think it can be a good "starter" app for somebody that just want to accumulate some sats and later consolidate them into a good LN node or a decent onchain UTXO.
