Okay so here is my problem the default messaging on my note 4 (Tmobile) loads MMS instantly, but google messenger takes a couple of mins to load it, it being with wifi or mobile data. Any solutions?
Are you using T-Mobile's wi-fi calling feature? MMS typically requires mobile data to be on. It's possible that Google Messenger isn't accustomed to using wi-fi calling for MMS. What happens if you're on mobile data only? Does Messenger work better that way?
