My AirTags are not updating their location anymore

Hi Dave_DE,

You mentioned that this happens with all of your AirTags, does it appear like this on any device you use to check the location or only your iPhone? Testing this will help isolate the issue a bit.

Let's also check out settings:

1. Go to Settings > Your Name > Find My
2. Be sure Find My iPhone and Find My Network are both enabled ( you can toggle them off and back on to force a refresh)
3. Be sure that your location services are enabled by going to Settings > Privacy & Security > Location Services

Find your keys, backpack, and more with AirTag - Apple Support

If this continues, reach out to Apple directly for further assistance. Depending on your region, you may be able to reach them here: Contact - Official Apple Support

Have a good one!
