Hi @[deleted], very strange! I'm not sure either.
Strange that it's fine on your other device. Are both devices the same version of iOS?
Did you export the whole session file to the other device or just the loop files?
Are new sessions out of sync or is it just old ones you load up?
Are you plugged into any hardware / interfaces. What happens if you unplug and just use the iPad speakers?
A video of the issue would be great if possible.
