(FIXED) Without Factory Reset - Deleting Apple Maps Data
Apple Maps was taking up 17.7 GB of data on my phone and it was horrible!! Only solution I saw on the Apple Forum from others was factory resetting, but after clearing up enough storage to download the iOS 18.3.1 update that deleted the maps data automatically- so somehow make space for the software update and it should clear the data once installed!!
iPhone 13, iOS 18
