Yes, did a couple of Tesco tasks today whilst on the way to visit the parents. The only gripe is the requirement to take 6 photos at the rear of the store and 6 at the front. This is okay for the larger stores (although a bit of a pain), but I'd find it quite hard to do surreptitiously in some of the smaller ones. The company is a US company, so perhaps this is something that will change over time.
If you go on the forums on the app (under help) you will see several people complaining about the excessive photo requirement bu there are replies from some of the long standing USA users who say they've complained about this in the past and the company does nothing so don't hold your breath!
They were asking for comments from new UK users as to how it compared to our other apps over here so I told them the photo requirements were excessive compared to BME etc.
I did one in a large Tesco and that was a bit of a pain to get 6 pics around the checkouts bearing in mind we have to keep people out of pics now with GDPR but they've paid it even though I did a few very similar shots. I've got quite a few around me in the smaller Tescos but I can't see an easy way to do the 6 pics in them particularly as they usually have a security guy hanging around there.
Incidently the US users were asking how much we got for the beer tasks and turns out they used to get a similar amout but it's been cut so they're not happy now they know we're getting more (at least at the moment)
