So far Bitcoin Wallat has never sent bitcoins sucessfully

[Responsive]

I am trying to use Bitcoin Core through the terminal. Testing out creating new address and receiving Bitcoin.

So far I have sent bitcoins three, and noon have been received.

The first two have red dot beside them.

The last one has a light grey dot.

What do these mean? The android wallet doesnt have a manual to explain hot to send bitcoins.

Now the grey dot has become a red shape. Like a 1/4 circle.
