Push notification reminders option not available
I have the Premium service and I want to set up push notification reminders to my iphone.
I have the app downloaded on my phone, but when I go into Settings/Reminders, it says "You don't have mobile devices with Todoist application installed."
And the option for mobile push notifications from the default reminder drop down menu is grayed out (not available to me).
Please send instructions on how to fix this. Thanks.
