Please help me. I have mined over 400ETN but it has not withdrawn into my electroneum app wallet.
probably best to log a support ticket - they can fix it easily.
It used to be something to do with the KYC status. Not sure whether this is still the case.
First, try stopping the miner from within the app, then start again.
Second, have you done both selfies? if so, how long ago?
Third, last option is to raise a support ticket as suggested above, https://support.electroneum.com (note, this is support account not your wallet login - so create one if you haven’t already).
