Loading Warning

Hello,
Problem
We already received some complains that the vehicles weren`t with the real position, but we`ve realized that generally, all these cases hppen because the app didn't loaded the units yet. In the screenshots you can see the case happening today in my phone. I opened it, the position seemed to be right, but after about 15 seconds, the position have been actualized in another very distant place.

Solution
Create an warning notification that the app is loading, like when you copy the notification description in the attached files.

Users
Will understand that the position isn't right because the app is loading.
