Google Voice App not prompting on outgoing calls

view story

http://androidforums.com – I have a new HTC EVO 4G LTE. I just installed the Google Voice app but it does not prompt me to select the GV or native number when making outgoing calls. I made sure that option is set in the GV app settings and I even set it to always use the GV number but the cell phone's native number is always used. Anyone have any ideas? Does anyone have this working on their HTC EVO 4G LTE? (General)
