With conversion of 1541 naira to a dollar, that should be almost $26 for monthly offer and $212 for annual offer.
I get that they want to earn money, but I can hardly imagine anyone would pay that much for a mobile wallet. I wouldn't even keep $200 in a mobile wallet.
I guess I'm not the target audience for these "premium features". I wouldn't want them in my wallet if they're free.
This morning I saw an update to Unstoppable Wallet, which fixed the LTC sync issues.
It's still not working the way it should: it takes hours for confirmed Litecoin transactions (sending and receiving) to show up in Unstoppable wallet.
