1 - When a retailer issues a refund, it messes up the “spent today” total. If I get a £45 refund and I spend £50 it says I’ve only spent £5 which is really confusing.
2 - From an aesthetic point of view, it would be nice to be able to remove refunded feed items. I manually tag everything that’s been refunded, so I don’t get confused about why things are there. But when some retailers (MoBike!) accidentally try to charge things to my account three times (!) and then refund a day later, it leaves a lot of litter.
