Same happening to me in iOS 13.
It worked briefly after updating to iOS 13.1 and then stopped working again.
I used sysdiagnose to retrieve swcutil_show.txt and it shows the next update time for the entry in my app to be: 0001-01-01 03:54:56 +0000
I was curious about this value, so I did some digging. It seems that this value is the equivalent of
NSDate.distantPast, that is, a placeholder that indicates that the AASA file has never been downloaded and should be downloaded at the next opportunity.
As to your big picture problem, it’s possible that you’re being affected by a bug that’s causing downloads to hang indefinitely. Can you try retesting this on the current iOS 13.2 beta seed?

I see same behavior for my app. The issue was there for iOS 13.1.2 and then was gone on iOS 13.2. Now it comes back on iOS 13.2.3.
Every time after a fresh install, my app's unviersal link stops working. Weirdly, aftet around 11:40PM of the same day, the links starts to work. I see this behavior on multiple days( with multiple installations each day) on the same device. Is this issue being addressed in the upcoming iOS 13.3 ?
Hmmm, I found this post because I feel like something very similar is happening with my app.
Universal Link in email is not recognised (I'm using Firebase for Passwordless Authentication), but after a seemingly random period it starts working - and I do feel it's late in the evening or overnight... (I'm in UK, so on UTC)
