Using a OnePlus One on CM11S 38R, PinNotif overrides a feature of Cyanogen.
As seen here
(view the two comments made to me, they show a detailed video & screenshot), there should be a "Ignore messages like this" option, but when PinNotif is enabled, the only option apart from App Info is Pin
I narrowed down the issue to PinNotif, since that when keeping Xposed enabled (read, installed) and only disabling this module, the option appears and works.
I think the issue is that when you go ahead and put an extra option for the context menu there, you put it in (hardcoded) index 1, and not in index length - 1
, but this is only an educated guess as a programmer. I'm not an Android developer, and hardly had time to look at the code for PinNotif unfortunately anyway.
