The CISSP Study completely stopped working upon today's Android 8.1 update on my Google Pixel 2 Xl. As I open the app it only loads a white blank screen during its startup and gradually after few seconds crashes itself after few seconds. Any idea how do I get it working again?
@BikasGaur are you referring to (ISC)2 CISSP Official Study? Assuming you purchased it on Google Play or elsewhere, raise this issue to the developers / vendor, since they'd be in the best potion to assist.
If re-installation had no effect you may have to consider modifying the app permission settings, depending on what device you have, as this can affect functionality.
