I noticed this on 
holiday - tried tapping to expand the text but it just seems to be cut off.
Any ideas? 
This also happens with merchant names that are too long for a single line. What are your thoughts on fixing this? Would you prefer to see a shorter description, text split over two lines, tap and expand functionality, or something else?
Personally, I like the idea of a shorter description. In your example, I feel it’s unnecessary to say “This exchange rate”, and instead just print the rate.
A shorter label would be ideal, if it included the tap to show extra information.
Im a sucker for knowing how much im saving with these conversions when abroad - I want all the details 
I would say remove the “This exchange rate is” and just pit what the exchange rate was. I think £1= $1 is quite obviously a conversion?
I agree that the text is also probably more verbose than it needs to be in this case, but the grey text is small enough that I think in principle it could wrap to a second line when needed. I have this same problem on an online purchase I made in €. It’s very frustrating to see the … and not have any way of discovering what text I can’t see!
This is a bug - it’s fixed in the next release of the app
