Yeah same for me. Thought my switch joycons were broke because of it but others having similar issues. Sometimes I switch to operator mode, energising dash, back to warframe and its smooth and feels good. Other times I get to operator, slide and nothing happens or can't get back to warframe mode or when I get to warframe mode, I can't use aim down sights or abilities because its like its stuck so I have to go into operator to get back into warframe normally etc etc etc. Very buggy and be nice if it's gets sorted so it's less random.
