Hello, Bella! 

I could not reproduce such an issue following the steps you provided. The belay option appears as it should. 

To start with, please join this topic and perform all the instruction from the first post. 

In case the issue still persists, please make a short video / a sequence of pictures illustrating the exact system time so that we could investigate the issue further. Thanks in advance!

When this was first reported, I couldn't reproduce it. I still can't, but it now randomly happens to me too.

Yesterday, my raids were a bit more apart and I got to test my theory.

So, you send galleons, then you cancel them, they are marked as cancelled (the timer stops and the "X" button is gone), but not removed from the list of those that are travelling ("Galleons Underway" tab) and not available to send again, which is a big problem. I then sent a raid to a random haven and cancelled it immediately. When that raid was fully cancelled (removed from "Underway" tab in Stronghold), the Market also refreshed and my failed-to-cancel galleons were gone (i.e., their cancellation was finished).

I have a feeling that Market sometimes doesn't receive the response from the server (to confirm that the galleons were cancelled) and then keeps those galleons hanging until the next server ping or the game is reloaded. A quick workaround would be to have the Market ping server frequently when it is expecting a change.

I hope this helps debugging.
