Babies R Us app internal error?

I'm not sure where to post this but for the last 3 days I've had problems with the babies r us app. I can't do anything with it. It keeps saying internal server error. I've tried logging out and back in, restarting my phone, uninstalling and re-installing, all to no avail. I'll call them tomorrow but in the mean time, has anyone else experienced this?

Website works fine though.
