Experiencing issues with eBay app, not allowing buyers to select options.

I normally put up lisitings that allows different options i.e size and I decided to check it out because of the new update. Using the eBay app (mobile) I tried to select the options and I get no response =(  Is this another hiccup with eBay app? 

Not looking forward to contacting CS....

 

is anyone experiencing the same issue?

Kind regards,
Kim
