How to copy a group of food entries from one day to the next. Haven’t figured this out yet...help!

You can copy a single item or the whole meal period. On the right hand side you should see three dots. Press those either in the meal period heading or next to the individual item. I think it then says “copy to” and you then select the day and meal period you want to copy it to. I use it all the time. Hopefully I have the steps correct since I’m going from memory.
