I found something in Chorme that helped me. There if you don't say YES the prompt to allow

ttd-fdp-ui-config-v2.app.intuit.com to access ... 

it creates a cookie with that response.  Go to  Chrome settings, select Privacy and Security and then under recent activity select ttd-fdp-ui-config-v2.app.intuit.com. Scroll to the bottom of the cookie  to the  "Apps on device" line and change it to ask or allow and try again. On the first download after I changed it to ASK  it again asked me to say yes to the download. I clicked yes but the download still did not work. Fo rno good reason  then I tried again and it worked! I went back to that cookie and it shows accept for "Apps on device". 

Good luck
