I wrote wrong. I have new IPad with 3G.
After update iOS no problem with 'data location'. That was cause.

You have stated you have a "proper iPad with wifi" but please note that the wifi-only model of iPad has no GPS receiver, as I mentioned in my first post in this topic.

If you have the model where a sim card can be inserted (the 3G model) then SkyDemon will be able to use the internal GPS receiver, as long as within Settings -> Privacy -> Location you have given SkyDemon permission to access your location.

Now I have proper IPad with WiFi but the same problem "on data location'.
It was work for 5 flights but today same problem?
What to do?

I was forced to borrow my wife's iPadair over the w/e as my faithful mini was locked out for some reason by dear Apple. Although everything loaded ok, when I tried to GoFlying at the strip it claimed there was no GPS signal even though the GNS2000 was shown as connected via Bluetooth. Usually works well with my iPad.Had to resort to Pilot 3! Had just loaded the latest version of SD.

I found that a Bluetooth external GPS works as well or better than most onboard GPS; You can position the external GPS anywhere in the cockpit where there is a clear view of the sky;

My IPad is without 3G. Only wifi.
I see that I bought wrong model

Thanks for help.

Is your iPad Pro the 3G model? If not, it will not have a GPS receiver in it, and will require an external GPS receiver before apps can use GPS.

Hi.
I've bought new IPad Pro and have problem with "data Location".
I'v reinstaled app and problem still exist.

I use also IPhone 6s without problem.

It could be a new IPad issue or something wrong with app? Have you heard about issue like that?

Thanks for help.
