That app needs help. I think the website does, too. If I open one of the instashops to look at it, often you can't click on the guidelines because it says you have to check in to do the shop, but why would I check in when I haven't even claimed the shop yet, let alone looked at the guidelines? I emailed tech help and of course, their explanation denied what I had just said.
Then there is the problem of the endless loop on the app I get stuck in that will pop up saying there is a newer version and it wants to save and update to the newer version but no matter what, you get the same newer version pop up no matter how many times it updates. Closing it out won't work but going to another device altogether will. Luckily I always have an ipad and an android cell phone with me on shops. (unfortunately, my ipad is ailing and failing and I am having trouble being ok with spending that much money for a new one).
Also glitchy and sucky is when I open a shop to look at it but don't claim it, it disappears off the map and list until I close the entire webpage out and go back in. Not sure if the app will refresh the same way. I wrote to tech help and more non-answers. I really like the concept of the site and app, just wish it would behave.
