I just have a quick follow-up question to this original question, and didn’t want to clutter the forum with additional posts. If I should make an additional post, please let me know.

So everything is working perfectly fine up until this point. I am able to add and remove Users as I please, so long as the User Field is initially populated in the Post.

However, when using a Multiple Select User Field, if no User is initially populated in the Post, and the following command is run:

$test = get_field('cb_roster', false, false);
print_r($test);

This returns nothing at all. Therefore, if I use something like:
array_push($test, $current_user);

Nothing will happen (since it doesn’t exist).

So, if I run the following:

$current_user = get_current_user_id();
$current_user = strval($current_user); //converting to string just in case

$test = get_field('cb_roster', false, false);
$current_user = array($current_user);
print_r($test);
print_r($current_user);

update_field('cb_roster', $current_user);

And then run:

$test = get_field('cb_roster', false, false);
print_r($test);

I get a blank value (as though it does not exist).

The output for print_r($current_user) returns:
Array ( [0] => 24 )

Which matches the format of the Array if it were populated from the Post.

Any input is greatly appreciated!
