Hello @unity_bill @DavidUnity3d I found an issue (for a while now and I was too lazy to report it (shame on me) but : The addressables package always throw error and warning when we try to initialize it with our distant catalog for our project. We have one project to build all our assets used by our 3 apps. But now when we try to initialize the addressables in a project there is one warning and one error throw on Initialize even if the initialization is ok. We can be sure the initialization is ok because we can reach and display the assets after those messages. Is it something that you already know ? Or maybe there is something different in the package that we missed to avoid this ? I can bring you some informations : With Addressables 1.2.4 : There was only the warning. With Addressables 1.3.3 : The 2 messages (as 1.4.0) are there with another error before them Code (CSharp): Exception encountered in operation Resource<ResourceManagerRuntimeData>(settings.json): Unknown error in AsyncOperation This error is present in Editor & in Runtime. With Addressables 1.3.8 : We only have the 2 messages (as 1.4.0) in Editor but 3 in Runtime with the same error than 1.3.3 just above. With Addressables 1.4.0 : Same behaviour than 1.3.8 Thanks !
