Debugbar info/alert/warning not showing in controller POST method call.

I'm getting no messages shown in the browser toolbar from a controller that's handing a POST - (update function call). Everything works fine in the same controller that are responding to GET requests. 

I get messages shown via Blade no problem.

I'm new to debugbar so maybe this is normal but I can't find a mention of it anywhere here or google. Any ideas?

Using Laravel 10.

Thanks.
