Sophos repeatedly asks to remain active in background

I am using Sophos Mobile Security on an Android phone running Oreo. At irregular intervals it asks two questions about allowing it to remain active in the background, titled "permanent protection". The problem is it asks these questions repeatedly, sometimes (but not always) when the phone reboots, and sometimes (but not always) when the phone wakes. Is there any way to not have to answer these questions repeatedly?

Thanks,
