Presto has fixed most of the glitches that made it difficult to check in when on site. And the GPS's have gotten more accurate too. The option to "report a problem" doesn't work anymore. For some reason, even though I have location enabled on the Presto app and my tablet GPS, I still can't check in using the tablet. I have to check in using my phone, then close Presto on the phone and take the pictures on the tablet. It's not a Presto or a service problem, it's a problem with this last replacement tablet and the folks at the phone company and at Samsung don't understand why, it always worked with the last 3 tablets just fine.
I have the opposite problem that ses has, the signal at my home is atrocious, and in most gas station locations, except for the very remote ones, there is better faster service. And even then I usually only have to drive down the street to a better populated area to find better service than what I would get if I waited until I got home. I can't get wifi or any type of broadband service here, only DSL is available for $90 per month. I use my cell phone as a hot spot for my desktop computer, it's faster than the DSL that is available and I don't have to deal with their constant outages which are sometimes daily and always at least weekly.
