I purchased premium on one android device and it is showing as purchased with an unlock date. After downloading and installing v4 on my second device (same GMail account) I find that it shows 30 days Buy Now button. When I select Buy Now and error message pops up that says "You already own this item". Reinstallation does not solve this problem. Buy Now does not go away. Will 1Password expire after 30 days on my second device?
