I have noticed "Siri Suggestions" must be on for this to work.
Doesn't help. If you toggle it off and on again then it works for some time and then stops again.
I filed a bug report, Apple asked for sysdiagnose, I provided that. We'll see.
You have Magical Moments disabled by one of your settings on your device. You have predictions that could be surfaced but nothing is being surfaced for one or more of these reasons:
1) You uninstalled the Siri App Suggestions widget from left-of-home.
2) CoreRoutine or “Frequent Locations” is turned off in Privacy > Location Services > System Services > Frequent Locations.
3) Siri Suggestions in General > Spotlight Search.
Response from Apple:
Seems that missing the widget is the cause of app suggestions not working but I have to test some more.
if it stops working again then re-add the widget. You might have to have it enabled in widgets for the suggestions to keep on working.Adding the widget to the Today panel fixed it for me!! I added it then immediately removed the widget and it still works. Plugging in headphones now shows the music app on the lock screen.
Thank you!!!
So if I understand corrently then they've removed the simple "Suggested apps" toggle and are forcing to use the widget instead?
