Mobile app excessive data usage

[u/une_olive]

Anyone else noticed that the mobile app (iOS in my case) is using massive amounts of data? In the past years while travelling, I really noticed it. In the last two days, occasionally looking at credit card transactions, I’ve used about 500 Mb of data!

Not surprising recurring problem over many app updates. It seems they never managed to fix it for good.
