Running 11.2 and seeing an odd bug: With no apps updating or anything else that should be causing it to happen, I'm occasionally getting the spinning "download" icon in the status bar for hours at a time, and the only thing that kills it is a restart. If I lock the phone, it appears to kill the process, but then it resumes again within seconds the next time I unlock. Obviously, it appears a process is hanging, but I have no clue which one. Anyone else seeing this? Is there a way to see which app(s) or systems are using the internet at any given moment? Thanks.
