I took one shop which I am doing today, just to see how they are on the app. I'm not really excited about it. I would much rather take the photos with my camera and upload from home, but I'll give it a go...once. Then I'll decide if I want to do more.
I also prefer to use my digital camera and upload in the comfort of my home office and was told I could do that. I was unable to sign in yesterday and after getting some help will try again today. Other than Presto the shop seems the same as in the past. Hopefully I won't get blocked again.
