@dev.sn When you say the libraries disappeared, are you referring to the libraries when you view them in Orchestrator? It’s normal to see them “disappear”, the blank Libraries screen means that you have not yet uploaded any libraries to your Tenant feed.
When “Host and Tenant Feed” is selected, you If you go into Studio → Manage Packages, The Host feed library packages will be visible in the “Orchestrator Host” feed. You will also notice an “Orchestrator Tenant” feed that automatically appears, which will show all the library packages that you upload to your Tenant feed (the blank screen in Orchestrator).
Note that you might need to restart UiPath Studio to see the Orchestrator Tenant option appear in Studio after changing the setting in Orchestrator.
@dev.sn with UiPath Cloud, if you choose “Host feed only”, the problem is that you do not have a way to upload custom libraries that you have created yourself, to share with other users within your Cloud organisation. You will notice that in Orchestrator, the “Upload” button doesn’t appear with “Host feed only” is selected.
Hence, if you would like to share custom libraries that you have created, your option is to use “Tenant feed only” or “Both Host and Tenant feeds”. Once you select these options you’ll see an Upload button and you can publish your custom libraries to Orchestrator.
So the Host library feed will always contain the latest libraries from UiPath, while the Tenant library feed can be used to share custom libraries that you have created with users in your Cloud organisation.
