Sending URL Parameter Into an Email for Native app

So here’s what I’m seeing immediately in the URL after I open the email link:

domain/version-test/index/sample:custom.insight?debug_mode=true?insight=1529289570164x782763756848939000

When the Index opens up, it’s running this:

Which is set to this:

image

What happens is that it loads the Index and then this part disappears from the URL:
?insight=1529289570164x782763756848939000

It becomes this:
domain/version-test/index/sample:custom.insight

So then I tried removing the “Only when” and opening the URL again - this time, it opens the Insight “View” Group, but with no content (since the id disappeared from the URL, I’m guessing it doesn’t have that information anymore and had nothing to load).

Any ideas why it might be getting rid of the id when the page loads?
