I downloaded the iPad version today and I was successfully able to import the existing rosters from my iPhone to my iPad

However, I was wondering if there was a way for any roster changes I make on the iPad (to existing teams) to be imported onto the iPhone and vice versa

I was unsure if this question was answered in the data sharing section

Thank You

We do not have a way to "combine" the data when the team already exists on both devices - data sharing only shows teams that don't already exist on the device you are copying to. You can delete the team from the device, then data share the team over again to get any updates.
