I've just deleted and recreated a location based reminder for probably the 6th time. I create it, it works for maybe 2 days and then I'll realize that I've left the location and NOT received a reminder. I keep checking that battery optimization isn't on for the reminders app, location is on, etc. Anyone have any ideas?
What model, carrier and software build do you have?
Software build: (settings > about phone > software information - last 4 digits of SW build number)
Have you tried any previous troubleshooting steps ?
