The app used to work well. But now discount codes you're emailed do not come off your orders. Cannot see how these app updates have been tested before launching the updates. Most recently the £10 was showing off my £57 order. Only when I saw the emailed receipt did I realise the app had not applied the £10. Customer service is no help. Easier to go direct to your local restaurants/takeaways and they'll save the commission that uber charge for their "service".
