I’ve recently started using the 
emoticon in the notes next to my Xmas related expenditure. Once I’d settled on the emoticon to use I went back and added it into various existing transactions on the Android app (for some of the older entries I had originally used 
or 
)
Then I searched for all the related expenses using the search facility on the iOS app. Only expenses where I had originally added icon at the time seemed to show. I was able to scroll back through the transactions on iOS and when I clicked on each one individually the notes/emoticon refreshed. When I searched again it then gave me an updated total including all those entries where I’d retrospectively gone to add Santa.
Just wondered if it was a bug relating to not refreshing the notes across devices for old transactions?
(We’ll be improving this in the future!)
