The new 60sixty App is slow and frustratig

I have used and loved 60sixty since it started, and ordered for both myself and my mom who is in a retirement village. It was quick and easy to order - 5 minutes and I'd be done. This new app is so slow, doesn't find what I am looking for - if i want coffee, i do not want a choice of coffee makers! It has just taken me 25 minutes to order 11 things. And this splitting deliveries is also annoying. how come so many things are now out of stock at the local checkers and have to be delivered from the hypermarket....later and at an extra delivery cost. Products like jam and dog treats. Not impressed. If they don't sort it out soon then I'm going to be moving to Pick n Pay. Much prefer Checkers, but the frustration and wasted time doesnt work
