I lost all Arena progress mid-run

What you were expecting to happen, and what actually happened?
I had 2 or 3 wins in the Arena on my iPhone. I played another round and won. So I expected to see 3 or 4 wins. Instead it said I had 1 win. I exited the Arena and went back to the world map then went back into the arena. Now its asking me to pay gold to start a new round, so I lost all progress.

What are the steps to make it happen again?
I’m not sure I can make it happen again but this is what happened.

  1. I played the first 2 or 3 rounds on the Arena this morning. I exited the app by pressing the iPhone’s home button while at the Arena screen where it shows your win count and the button for the next round is active.
  2. Several hours later I re-opned the app and it was still on the Arena screen. I pressed the next round button and played and won.
  3. After that it said I had 1 win, then as I said above it lost all progress completely.

No sorry.
