I cannot completely tell from the app pictures on the site, but it would worth thinking about it how much English people need for delivery? E.g. Uber is in English here, and was using it pretty fine without much Chinese. It's less of an issue for me, have an "everyday" level of proficiency, but in general. Also, do you have different apps for the different markets? If it's the same app everywhere, then it would make sense that the people can bring the "service" with them e.g. going from Taiwan to HK on a business trip, or Singapore for a few months work stint (or any other direction), and they can still use it the same way. It drives me crazy to no end when there's an international company, and language is completely tied to the location. Your case make a bit more sense than others, and it's a ton of work, I know. Just some thoughts.
