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?
Other than waiting for an update to the app, my only suggestion would be to try uninstalling and reinstalling the app if you have not already done that.
@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.
