After taking off with the air 2 a message said gps signal was weak despite showing 15 or more satellites and the maps wouldn't load . It also temporarily went to attitude mode . I was flying whilst streaming data from my phone so I should have had maps. Because of this I brought it back down to land. If this had happened while flying much further away would it still have been able to auto return if I have no GPS or maps . It's the first time this has happened. I was in a very rural area
