Resolved Unable to update content post release on iOS and Android devices (1.21.2)

Hi everyone!

After many hours of searching a solution, reading documentation and same problem posts, I am actually stuck on my mobile game development : I can't upload new content on devices through addressables.

In the editor, everything works fine. I also can test my upload via the "Use existing build (iOS / Android)" that detects new uploads and run as expected.

I am using Addressables 1.21.2, my workflow is the following :
-Building my app, then collected the bundles generated by this build.
-Uploading my builds to Unity CCD (buckets are private, I use an access token but nothing wrong about that in the console). I upload ALL the files (bundles, catalog.json, catalog.hash)
-Testing on the editor, using "Use existing build (iOS / Android)", everything is fine.
-Testing on my device (the build I made before). Everything is fine.

Now, I change the color of a material of one of my bundles.

-In the Addressables Group window, I choose "Update a previous build"
-I've got a new bundle of the one I've changed.
-I upload once more EVERYTHING. I now have a modified catalog.json / catalog.hash. I've also got 2 bundles of the edited bundle but with different name)
-I test on editor with "Use existing build (iOS / Android)", everything is fine.
-I test on device (no new build so). Update isn't detected...

My group's parameters (they are all the same):


My Addressables settings (NB: "Only update catalogs manually" isn't toggled anymore)

• I have two profiles : one for Android, and one for iOS (I know that I need to builds bundles separatly for both of them). The problem is exactly the same on Android or iOS.
• In my C# scripts, at the beginning, I call Addressables.InitializeAsync() (not sure if necessary...)
• I don't select the ".bin" file when I click "Update a previous build" as it is supposed to be automatic in 1.21.2
• My "Remote.LoadPath" always uses the "latest" badge, no matter the profile

Can someone help me pls ?

 

EDIT : I (finally!) fix my issue by updating manually the catalog.
Letting it updating automatically by the system only work on the editor but not on Android / iOS devices.
I suppose this is a bug from the addressables.

Here's my workaround :
> In the Addressables Assets Settings, check "Only update catalogs manually"
> When you want to update your catalog, try with the following C# code :

Code (CSharp):

1.         //Initialize Addressables
2.         AsyncOperationHandle initializationOperation = Addressables.InitializeAsync();
3.         yield return initializationOperation;
4.         if (initializationOperation.Status == AsyncOperationStatus.Succeeded)
5.         {
6.             AsyncOperationHandle checkCatalogOperation = Addressables.CheckForCatalogUpdates(false);
7.             yield return checkCatalogOperation;
8.             if (checkCatalogOperation.Status == AsyncOperationStatus.Succeeded)
9.             {
10.                 Debug.Log("Addressables : CheckForCatalogOK");
11.                 var result = checkCatalogOperation.Result as List<string>;
12.                 if (result != null && result.Any())
13.                 {
14.                     AsyncOperationHandle catalogOperation = Addressables.UpdateCatalogs(result, false);
15.                     yield return catalogOperation;
16.                     if (catalogOperation.Status == AsyncOperationStatus.Succeeded)
17.                     {
18.                         Debug.Log("Addressables : Catalog updated");
19.                     }
20.                     else
21.                     {
22.                         Debug.Log("Addressables : Failed to update catalog");
23.                     }
24.                 }
25.                 else
26.                 {
27.                     Debug.Log("Addressables : No catalog updates");
28.                 }
29.             }
30.             else
31.             {
32.                 Debug.Log("Addressables : Failed to check catalogs");
33.             }
34.         }
35.         else
36.         {
37.             Debug.Log("Addressables : Failed to Initialize Addressables");
38.         }
39.         yield return null;

Note that you can't call "Addressables.UpdateCatalogs()" without "Addressables.CheckForCatalogUpdates()". Otherwise, it will throw an exception if you haven't content updates.

Operations aren't released voluntarily.

I tested the above code, it works for me on the editor, an iOS device and an Android device!
Maybe I should report a bug for the Unity team ? (I'm using 1.21.2)
