I signed up for Monzo this week! Generally loved the whole experience but noticed that almost every action I take in the app has a significant delay.
I’m running the iOS 13 developer beta 4 which may be the real culprit, but tapping list cells for the first time (consequent loads of the same view we’re fine) and logging in via the magic email link were super sluggish. I’ll try to repro in a screen recording (as I mentioned, after first load, consequent view loads seem fine) but just wanted to flag in case it needed investigation!
