It won't reset your progress even if you do a battle. I was at round 18 and it disappeared and came back a few minutes later at round 1 so I just battled and got all the way to round 4 then when when got back on it had me right back to where I was be our it disappeared at round 18. So it doesn't matter even if you do battle.
