I left my wallet staking for 1 week, running 24/7, but till now no extra coins on my wallet...

If i move on the icon in the bottom left, it always says:

"Staking.
Your weight is xxxxxx
Network weight is xxxxxxxxx
Expected time to earn reward is 3 days
"

sometimes it says "2 days".

So, how can I get my reward?

PS: i tried to close and run the wallet but nothing changes...
