I have the same exact issue , and so I contacted Logitech support, and obviously they only offered me a 30% discount to buy smth new because it’s been 3 months over the warranty expiry. I then told them that can they please forward my request to the higher authorities, cause paying 200 dollars and only after 1 year and 3 months not working so I deserve a replacement, so maybe try contacting them. I’ve tried absolutely every thing for almost 6 hrs, not working.
