I have Viva Learning with the trial licenses assigned to about a dozen people. All users have Exchange Online. Here's the problem. The 'people picker' aka 'Recommend to' does not work properly. This behavior is reproduced with more than one M365 admin account. We have tried with 'Knowledge Admin' Role, we also confirmed using an account with Global Admin.
This 'People Picker' does not work like any other M365 app. When searching for one particular user, they do not come up at all. First name, Last name, Partial, they just don't come up. And for others, when searching by First name, they do not show at all. When searching by another name completely, their name will come up. For example, type in Smith and you find results for 'Nolan James'.
We have reproduced this on Teams desktop app on Mac and Windows 11 with different user accounts. It is really strange. The funny thing is that the one person who really wants to see the recommended content is our CEO and his name is the one that doesn't come up at all.
It is hard to post on this but here is a try. In this case, a search for 'CJ' was entered. However, not a single name that was shown in response has 'CJ' as part of their name nor are those two letters contiguous in any of the names returned. Why would 'Madeline Albright', for example, be returned as a name matching 'CJ'? This is really strange.
