Help me restore my skins ?

Hi !

I have 2 androids phones, the old & the new one.

This morning I bought a skin with the new one, but when I click to "restore purchases" on the old one, nothing append "Alert 0 items restored".

I tried to uninstall and reinstall the game, all my previous purchases are here (all the specials tribes and an Elyrion Skin), but not the last I bought.

Any idea ?

Thanks

Edit: I asked for a refund and bought it again from the old one. Now the skin is still locked on the new one...

Edit 2: I tried to buy it on both phones. There is an error just before the 2nd payment and then finally unlock the skin on the 2nd phone.
