Genshin Mcdonald Code How to Find

If you ordered the McDonald meal and have not received a code after 30 minutes to and hour after purchasing, use the search function in your emails for "Got ur Genshinn Impact rewards". For some reason mine didn't show up in my primary inbox. However it does seem the code only works for one item per order. So if you ordered both, you seem to only get the meal code. I hope this issue gets resolved.
