Today when I tried to send (return) gifts to neighbors the game defaulted to jewels. This was only when trying to use the return button in messages. If I visit the neighbors kingdom and click on the gift icon, I can choose the gift.
I did force close my game, but will have to wait until tomorrow to see if that worked. (I sent all three gifts before thinking of trying that.) I did install the latest app update last night and am wondering if this is a new bug.
