Hi
How can I attach images or pdf. file to crowdsource polling app???
thank you in advance for your answer
Look here:
Polling allows files such as photos and PDFs to be submitted along with comments. To turn on this capability, enable attachments on the table layer prior to publishing or from the details page of the feature layer item.
