1sec response times on almost any touch event. (comments on the forum suggest this is because they use O(N) algorithms somewhere, and after 2y worth of events the app slows to a crawl. doesn't inspire confidence, to be honest.) This is not my experience on a few different iOS devices over the years - things respond pretty much instantly (iPhone 6 and 8), never seen 1 second waits. There's something wrong with it on your phone (not sure what, and that is an old model), but that is not the experience on a newer phone. I have a few years of transactions in there, was an early user so it's not that either. Perhaps SE particularly suffers though and it's just masked because I have a faster device. I do hope their friendly support can cope with their growth, I agree it's one of the best bits of the customer experience.
