Saving ID to wallet doesn't work – Delta Dental Mobile Review

Clicking the option to save the id card to the wallet does nothing. The method to set a preferred dentist is obscure. (The only way I could do it is to search for a dentist and then click the tiny star at the top.) Why can't it default to showing the dentist you've visited? Also, can't get help: both the App Support and Report a Problem links just go to the Delta Dental "about" web page, which has no links to get app support or report problems.
