its happening to me too, And i dont know how to fix it, a comment say to check your settings but it doesn't work for me, and im on android.
May i ask on what category because i tried checking everywhere on my settings, im downloading it on my phone.
For some reason when i download it, it is always download halfway before saying that is either forbidden or i cant download. And i do have more than enough space, if you could tell me how to fix this i would be very grateful.
