I was flying near an airport but received an auto approval for 300' AGL through LAANC. Also completed a geo unlock successfuly through DJI. When I got to my site I received an orange warning in upper left corner (see photo). Any idea how to eliminate this altitude restriction?
Thanks!

There are different types of zones, with different restrictions.
It looks like you are in the "Altitude Zone", an altitude restriction zone, this type of zones is located along the take-off / landing sector of the runways.
Automatic unlocking works only for "Authorization Zone", but not for others, that require a special unlock request..

Different zones specially with aircraft flying over constantly will give you AGL limits.
