Unable to donate ballons

As you can see when I try to donate balloons, all I get is the spinner.

have you tried refreshing the game?

All the usual things like refresh and clearing cache made no difference, but the problem whatever it was has fixed itself now after 4 hours. Only thing I can think of was it got stuck due to too many people trying to donate at the same time.

could have been.
still really strange though glad its fixed again :)
