Enabling location services for Exposure Notification Availability Alerts
For &quot;Availability Alerts&quot; to be enabled, I believe you need to have 3 settings turned on:

Location Services
Location Alerts
Significant Locations

It looks like you might not have &quot;Significant Alerts&quot; turned on.  Go to Settings -&gt; Privacy -&gt; Location Services -&gt; System Services and turn that on.
