Tablet mode needs work

I have been complaining about how broken the tablet mode is for like 2 years and nothing has been changing for the better. And now Android tablets are making a comeback in the market and this app is still borderline unusable and has almost zero resize-awareness. The emoji/gif/sticker ui bases its width off of the entire horizontal resolution of the tablet, not the horizontal width of the app, meaning that if the app is in split screen half that UI is off the screen. Also, when the app is launched in full screen (it doesn't change between the ‘desktop’ UI and mobile UI unless it's completely closed and re-launched) the channel switcher (that's not hidable) takes up some of that horizontal space so the stickers tab and right side of the emoji/gif/sticker UI is still off the page!
