I first bought the premium version on my iPhone on the 3rd of May. But my diarium diary on my macbook and my iphone were not syncing together. I was backing up to my google drive on my iphone. The diarium app on my macbook kept prompting me to upgrade to the premium version if I want to sync to google drive even though I had already bought the premium version on my iPhone. And I am using the same apple ID (karishmaraimalani27@gmail.com) on my phone and mac. On the 9th of May i opted to upgrade to premium on my mac too as I really wanted my diaries on my mac and iphone to sync together. I was hoping that the system would realise that I have already paid and it wouldn't charge my again but i ended up getting charged twice.
