I would like to know why Diarium, even though I have paid for it, when I enter the options menu from my Android phone where I made the payment of €15.99 and the first installation of the application, does not show me the Pro option, while on my tablet, also Android, when I enter the options menu, it shows me the Pro option, while I have normally connected and synchronized my e-mail perigreece@gmail.com. What I want to say essentially is that it gives me the option to pay again, from another device, for the same account, while I have already paid for it. Normally, this option should not appear on my tablet.
I would also like to know the procedure I need to follow to see Diarium on my laptop, without of course paying for the same account. There I need it so I can synchronize events.
