I just re-onboarded an Android device to our M365. So far so good: I was able to re-connect to the standard vault on my business OneDrive, as expected.

Now, I'd like to add shared vaults stored on SharePoint/Teams sites that work just fine on Enpass Desktop. I'm following these instructions: Adding shared business vaults to your Enpass app but there simply is no option next to / underneath my business email to add another vault. No "+" button, either.
(there is an option to add a personal vault, tho)

All my desktops show this option and are connected to these shared vaults and work as expected.

More details about the setup:

1. Enpass runs in an Android work profile, managed by M365. Since I have normal access to my personal business OneDrive as expected, I see no reason why there shouldn't be access to SharePoint sites either. Enpass must run within the work profile, because only apps within the work profile have access to work resources.
2. Other Apps in the work profile, such as Teams, Edge and OneDrive can access shared Sharepoint libraries just fine.
3. When activating Enpass for the first time, I select the "Business" option, using the work/business email account I have, which is licensed. Activation succeeds apparently without issues.
4. I am signing in with my (only) work account. Authentication appears successful, since Enpass can access the standard vault on OneDrive.

Naturally, Enpass is on the latest release, as guaranteed by Google Play.

Why is there no option to add shared cloud vaults?

Never mind. I went through the process again after re-installing the app fresh.

This time, after adding my business OneDrive, all the vaults I have access to on SharePoint just showed up without a need to manually add them. So while my problem is solved, I'm not sure if that is expected behavior? I think I'd prefer it if I needed to add KNOWN vaults on KNOWN sites, instead of just "all" of them.
