The Battle Arena is working correctly for me.

Please provide more information so we can investigate this further.

What type of connection are you using (Wifi or cellular)? The Arena needs a stable connection to correctly save your progress.
What rounds are you experiencing this on? Which Dragons?
Are you experiencing unsaved progress with any other part of the game?
