No I have not seen that, at least not so far. I only have a single Foreign Currency. But I guess I don’t type numbers very often - I use the Denomination Buttons on the Left, or the ALL button almost exclusively. Do you have “Auto-decimals” enabled?
Yes, I made the switch and it went fairly smooth. But I took over a month to develop and test it too. Not for the light of heart. I switched both of my Venues and things are working great!
