Long transition time

I downloaded this after buying the wifi iOBD2 adapter for my 2000 Jeep Cherokee. After trial and error of finding out that Chrysler or Dodge didnt work because there was no selection for Jeep, the "other" selection worked. But selecting something and then selecting to go back seems to take a long time to transition back, and sometimes freezes and crashes the app. Its doesnt link up to everything, but I figured it wouldnt, being an older model jeep. I just hope they can fix the issues with the app to adapter crashing soon
