Slow loading or lag

My problem only happens when on mobile.Text channels or visual channels are loading late/slow. My internet connection is as usual but when i enter the app everything loads slowly including my profile. In fact, even though the messages I sent were sent across, it shows as not sent to me. My profile loads late when i go to settings. Sometimes i even close the app and open it again because it doesn't load. I can't edit or add emojis to newly sent messages. When I try to send emojis that work flawlessly on others on the server, it either stays as text or does not send. Example: :KEKW: normally it should be converted to thumbnail but it stays as text and now it's getting very annoying.
