i have a location symbol with a line through it on homescreen, what does it mean

Why do I have a arrow with a line through it on my screen

The root cause is that the location in the Weather app is not set to be "always".

Hello krusty1,

Just to confirm, are Location Services turned off on your device? Does that icon still appear if your device is restarted? That information will help us get a better understanding of the situation.

Please check out this link, which explains how to review and manage Location Services settings, which may help: About privacy and Location Services in iOS, iPadOS, and watchOS

Turn Location Services on or off

You can turn Location Services on or off at Settings > Privacy & Security > Location Services. You can turn Location Services on either during the Setup Assistant process or later through the Location Services setting. You can individually control which apps and system services have access to Location Services data. When Location Services are off, apps can't use your location in the foreground or background. This will limit the performance of various Apple and third-party apps.

If you would like to reset all of your location settings to the factory default, go to Settings > General > Transfer or Reset [device], tap Reset, then tap Reset Location & Privacy. When your location and privacy settings are reset, apps will stop using your location until you grant them permission.

Settings > Privacy & Security > Location Services.

Settings > Privacy & Security > Location Services > System Services.
