restoring purchase

hello,
I purchased a PRO feature before login to muse score.
I now created an account to use MuseScore on 2 different devices (iphone & ipad). I am able to hit "restore" on the device I was using for the purchase and get the PRO feature (iphone) but it won't let me use it on my ipad (which is connected on a different i-tune account).
Can the PRO account privileges be transfered to my MuseAccount ?
Thanks
