Norton App Lock doesn't work after restarting my tablet
I'm having an issue with "Norton App Lock" on my tablet "eZee'Tab7Q15-L" with Android 6.0.1: The app doesn't work after rebooting the OS, I have to launch the app previously and then it works.
I also have an older tablet with Android 5.0 and the app works after rebooting the OS without the need of launching the app previously.
I already tried to find some questions on internet and I saw some people who they had the same issue, but nothing helped me.
Anyone could help me with this? I just need to make it work after rebooting the tablet without launching the app previously.
Thank you in advance!
