Readdle Spark?
Has anyone else noticed that the IOS App "Spark" by Readdle appears to install itself without asking permission? This weekend, I received two emails from friends who were using Spark as their email client on IOS or Android. After reading the messages in my own Apple email client, I suddenly found all my emails hijacked from the Apple default app to a newly installed (without permission or authorization) version of Spark, complete with notifications turned on (I keep my email notifications turned off), and it now the default email client. I deleted it immediately, but noticed this morning that even on my Macs, there is now a Readdle folder installed inside my normal email box.
It is my understanding that other than Apple-created apps, NO APP can install WITHOUT PERMISSION or by granting permission to download through the Apple Store. Interestingly, I don't seem to find the Readdle Spark, actually just "Spark", in the app store. Where is this coming from and why. It seems like a major security breach.
