I use to a terrible time if I had shops in rural areas without data. If I finished a shop I had to drive somewhere with data to sync. I was losing money during to find wifi.
I emailed gigspot about missing photos and if course they said it was my fault, I know it wasn't.
Anyway, they told me about a nice trick that u didn't know. If you click in your profile in the top right you can change the setting so you don't have to sync between shops. I love it, it saved me a lot of driving and now ill take more if the rural shops
