Unable to expand MemberOf using Microsoft Graph .NET SDK using Delta Query - microsoft-graph-api

Question

Expanding properties doesn't seem to work when using Delta queries. It works fine with regular user query.
Is this a limitation in Microsoft Graph API?
var usersInfo = graphServiceClientWithApplicationPermission.Users.Delta().Request().Expand("MemberOf").GetAsync();
// Add inital request users
foreach (var userInfo in usersInfo)
{
// Member info doesn't seem to be expanded even if $expand=MemberOf is sent
if (userInfo.MemberOf == null)
{
userInfo.MemberOf = await applicationPermissionsClient.Users[userInfo.Id].MemberOf.Request().GetAsync();
}
// MemberOf is now populated ??
}

Seems like this is another limitation of the Microsoft Graph and not supported.
Optional query parameters
If a client uses a query parameter, it must be specified in the
initial request. Microsoft Graph automatically encodes the specified
parameter into the nextLink or deltaLink provided in the response. The
calling application only needs to specify their desired query
parameters once upfront. Microsoft Graph adds the specified parameters
automatically for all subsequent requests. For users and groups, t
here are restrictions on using some query parameters:
If a $select query parameter is used, the parameter indicates that the
client prefers to only track changes on the properties or
relationships specified in the $select statement. If a change occurs
to a property that is not selected, the resource for which that
property changed does not appear in the delta response after a
subsequent request. $expand is not supported.
For users and groups beta (preview) APIs, scoping filters allow you to
track changes to one or more specific users or groups by objectId. For
example, the following request:
https://graph.microsoft.com/beta/groups/delta/?$filter= id eq
'477e9fc6-5de7-4406-bb2a-7e5c83c9ae5f' or id eq
'004d6a07-fe70-4b92-add5-e6e37b8acd8e' returns changes for the groups
matching the ids specified in the query filter.
