I've been developing a public survey to send out to some volunteers. For the most part, they are not having issues following directions on how to download the app and then open the deep link from the email I sent. HOWEVER, I've had at least two volunteers tell me that they can't click the link in the email and open prompt the survey to open. They are both using Android devices.
Now - I am not a developer, so I've read things here and there about the links and Survey123, but it's totally over my head. Can someone walk me through what's going on, why Androids won't open these links, and what I need to do to get these people up and running? In laymans terms?
