Game is 100% unplayable for me on Horizons after today's patch. I get constant connection issues and black screen crashes. I have found no workarounds or fixes to fix this issue. I hate to say it but Odyssey should have been delayed and they need to test their patches. I JUST bought a HOTAS for this game and if these issues aren't resolved I may just get a refund. I love this game but since Odyssey's release the game has gone downhill at a steady rate.
Get the refund sooner rather than later if you aren't playing imo, you can always buy it again in the future you might not be able to get a refund in the future.
