[Cortana] Location based reminders won't work anymore

[Windows Central Question]

Hey all,

I have a problem with cortana and it's location based reminders: They won't work anymore since the anniversary update on Windows Mobile.

I guess I have tracked down the issue: If I look up in the position settings of Windows Mobile I see some options like "location service" and "location symbol" (I use a german phone, so the translation could be wrong) aand I see "location history" (Positionsverlauf). "If the location history is activated blahblah" but I do not have a slider to activate or deactivate it. Why this is important (i guess)?

Because if I scroll down to the apps which are allowed to use my location I see Cortana greyed out and right under it it says "The location history has to be activated to use Cortana" (Der Positionsverlauf muss zur Verwendung von Cortana aktivert sein.)

All other reminders work like a charm, only the location based reminders won't work. Has anyone an Idea how to fix that?

Here are some screenshots (unfortunately in german) that may help?
