Hi!
The rewards in Appics go directly to your voting power, it is not necessary to power up, for powerdown you must be logged in with the active key.

As for the Steemit accounts, it may be some isolated cases but many have entered the network and that is the only way, you could tell me what error you throw up and I am glad to be informed.

If would you like to contact me via telegram, locate me as @Bitcoinroute and I will gladly assist you.
