Well it hasn't been an app, but I will wake up my phone and get notifications from various apps stating something to the effect of "blank app needs location data to function properly or whatever" and then I check and the actual location service has been checked off and I have to turn it back on. I haven't identified any pattern or usage that may be triggering it. I also haven't installed any new apps in months so it may just be the launcher. It's been through regular updates though so I'm not sure if that's it either. Currently using Microsoft Launcher FYI.
