"Set Vibrate on Ring State" throws exception after reboot

[kintrupf]

I have a flow which sets the ringer volume and state if the phone is connected to my WiFi.
When this flow is executed on phone startup the action Set Vibrate on Ring State always fails.
If I then execute the flow manually it succeeds and sets the ringer mode.

Automagic Build 1.30.0-dev from Jan. 30, running on a rooted Nexus 5 with Marshmallow 6.0.1 ( Feb. 1 Patch).
Automagic Workarounds is installed, too.

Hmm, works for me. Could you please uninstall Automagic Workarounds and reinstall the Workarounds? When it still fails, reboot the device once. Is 'Modify system settings' in System settings->Apps, Cogwheel, Automagic Workarounds set to Yes?
On a rooted device you could also uninstall the AM Workarounds and try again since I've added an alternate workaround when root is available but the AM Workarounds are missing, however I would be interested to know why the AM Workarounds fail since this will be the mode most users will use.

I reinstalled Automagic Workarounds, during installation "Modify system settings" was listed as permission. However, once installed the app info showed no permissions at all
Rebooting produced the same error as before.

Then I uninstalled Automagic Workarounds, unchecked and rechecked "Root functions" in Automagics preferences (to be on the safe side) and rebooted.
And it seems I don't need the Automagic Workarounds after all! This time the flow executed perfectly during startup
Thanks Martin!

The permission Modify system settings is a special permission so it's not listed under system settings->Apps->Automagic->Permissions but only under System settings->Apps, Cogwheel. Sometimes the system gets into a state where Modify system settings is ticked but is actually not granted to Automagic. Deactivating and activating the Allow modify system settings can help. I have yet to find the cause for this strange problem, maybe this also happened to the AM Workarounds for some reason.
