Blank apps and icons for cellular data usage
Under Settings > Cellular, in the "Use cellular data for" list, the first two rows are for a couple of unknown apps, missing both title and icons. I assume they are remnants of apps I deleted but I am concerned they may be malware or some other bug. I have tried resetting my phone and made sure it was sync properly with my apps on my mac, but these missing apps are still there (see photo). Any suggestion on what these blank apps may be, and whether I should turn off cellular usage just in case? Thanks.
