While attempting to get data from two devices to come together I have lost the majority of my data
While using the manage data in the account tab in iscorecentral, I "copied" data from one device to the other.
This seems to have replaced the data that was there before instead of adding to it.

Is there a way to get this data back??

That is correct... transferring the data replaces the data which is why we pop up a confirmation saying this will happen, and then an input box where you have to actually type the word "YES" confirming the transfer.

If you email your customer ID to support@iscoresports.com and remind us what you did, we can see what data can be recovered for your account.
