Respectfully, I disagree. The biggest issue I encounter on Presto just doesn't ever go away. You have to be on site to "log in" and then obviously, you have to be on site to enter the form and take the photos. Actually, the shops could be completed after logging in at the site, by driving away and entering later....but that generally creates more work. Anyway, the big issue that I sometimes encounter is connectivity...when connectivity is a problem, for whatever reason, Presto is hugely (Trumpism) difficult to use. Waiting to see that the shop is received sometimes takes quite a few minutes!
A note on Presto "appeals": I just did one the other day which was rejected, and less than 24 hours after the shop was completed. I decided to "appeal" but checked the map first, and saw my shop (which I appealed) already re-posted. They had NO intention of honoring my appeal, and, as suspected, they ignored the appeal! No reply, no feedback, crickets!
