EO Tracking

I have a similar problem.
Only went a few Ks and it shows my track correctly going there but return journey along the same route is a straight line from there to home.
Ths is my first use of system so maybe I did something wrong but I don't think so.

dont know if this is relevant , but when i'm log/route tracking on my GPS
i can sometimes get a straight line if gps loses satellite reception ?

I know I opened uTrackme turned on Background Tracking then sat the phone on the centre console, drove to Geelong, picked up my grand daughter and drove home. I never got out of the car or touched the phone until I got home when I turned off Background Tracking. It has to have been on because it showed that I was in Geelong, but got there across the water.
