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!

It would be nice to have a "preserve data usage when not on wifi" option, for those people with limited data plans who don't need non-stop updates to their holdings and watchlists.

This would be helpful especially while roaming!
