iphone 8 ios 12.4 something strange happened yesterday. my data counter reset it’sself and it never did that before. since then some apps are missing from cellular settings and i can't turn them on or off. here's what i tried; reboot phone, soft reset phone, reset network settings, delete and reinstall effected apps. i don't want to reset the whole phone because i would have lots of apps and media to redownload and my internet is under 1 mbps. i also am trying to avoid updating ios because i am jail broaken. please how do i fix this.
