It is not. I have several Android/GoogleTV 14 devices and Stream Links work on them. It appears, though, you are running into specific apps that are having problems.
As I said, you'll probably have to play around with this one. Based upon what I've seen, Paramount+ doesn't seem to be happy with anything direct, so you might have to deal with just a generic launch. Try a Stream Link Mapping of anything that contains paramountplus and replace with https://www.paramountplus.com and see if that works just for app launching. From there, you can try the subareas, but the problem appears to be on Paramount's side, so you'll have to reach out to them. Tell them they wrote deep linking incorrectly in the Android Manifest.
@miles, @tobycth3, @Jean0987654321 can you comment on this? When last we discussed in February everything was happy, but maybe something changed?
Looks like Disney broke something in the Android Manifest because this was working before. Since the standalone version of this app is going to be discontinued sometime in the next few months, I doubt they'll fix it. In the short term, you could do a generic mapping to at least open the app at https://www.hulu.com/open. My recommendation is do the Hulu to Disney+ mapping because that works in 98% of situations (some content still isn't in Disney+Hulu yet, for reasons that are beyond me, including a couple of Hulu Originals I know about).
In case anyone is interested in my analysis, here's a part of it (from my AI buddy):
Disney+ succeeds because:
✅ It accepts any path under the domain
✅ It uses server redirects to normalize links
✅ It does not require strict pathPrefix matching
✅ It does not rely on the app to parse the incoming URL directly
Hulu and Paramount+ do the opposite:
❌ They require strict pathPrefix matching
❌ They do not redirect /watch/{id} or /shows/{id} into a normalized format
❌ They rely on the app to parse the incoming URL
❌ They require App Links verification to succeed
❌ If verification fails, Android silently ignores the link
This is why:
✅ Disney+ links “just work”
❌ Hulu links often do nothing
❌ Paramount+ links require rewriting
