There are WAY to many issues with BO6 split screen zombies

Me and my friend played split screen on Xbox Series X for around 8 hours and encountered too many problems to the point that it is borderline unplayable. Here are all the issues we encountered:

• No split screen pause or save and quit
• The game simply will not load into the map, it will some times take 2 or 3 goes and the game needs to be fully reset
• SAM trials will not work at all, you can activate them, but then you can't see what the challenge is and no purple zombies spawn
• Going into the menus in game makes it very choppy for the other person
• The round counter gets stuck on one screen (e.g. it will stay stuck on round 5 on the top half but be normal on the bottom half)
• All of the kill notifications from player 1 only appear on player 2 screen
• The menus before the game starts are unusable, guns can't be modified and augments can't be researched. We had to exit split screen and change all that stuff in a solo lobby individually
• Power up icons don't appear for the top screen, only the bottom screen
• Some times there will be no audio for player 2

One thing I can say is that the game plays fine performance wise. However there are far too many significant bugs that need to be addressed. I know that split screen is quite niche these days, but they should not release it in such a state as it is now, very disappointing.
