I purchased a battery-powered 2nd Generation Nest Protect on February 18th, 2022. Yesterday afternoon the smoke sensor failed and was beeping intermittently. The app said that it could need to be cleaned. I used a can of compressed air to try to clean out the sensor and restarted it - it failed immediately. I am writing in compliance of the Limited Warranty listed on the Nest website included below. Please advise.
