In the Norwegian map, the frequency of Farris TMA (south east part of Norway) is wrong for VFR flights. The TMA has separated radio traffic between IFR and VFR flights, and it is the IFR frequency 134.050 that is listed in the SkyDemon app. For VFR flights, 124.35 should be used. This frequency is actually listed correctly under "notes" when clicking the "134.050" frequency in SkyDemon, but obviously this makes it impossible to know which frequency is correct.  See attached images. I've included a screen shot of the Norwegian AIP. 

For clarity and my suggestion: 

Change the frequency immediately listed from 134.050 to 124.35 as I believe most users of SkyDemon fly VFR, and under notes list "VFR: 124.35. IFR: 134.050". This would make it clear which frequency to use under which rules. 

How should this be reported?
