Ring movement sensor 2 - faulty or not fit for purpose?

I hope somebody can help resolve this, because if it’s not faulty, I don’t know what else to do, the alarm is no good to me as it is. Basically, I’ve had a home alarm system for 8 years, recently replaced for the Gen2 Ring alarm. I’ve got the full kit, with additional sensors and siren. It’s been great, but on my 1st attempt of going away for 1 week, and really leveraging the remote monitoring, I was faced with 3 false alarms. All caused by the sensor in my conservatory. I’ve now moved the sensor to a corner, but still see detections throughout the day which would result in the alarm sounding. It did not do this initially, and has only ever done it in the day. It does get hot in there, no way around that, but my old system never had any issues. I’ve already got the sensitivity set to the lowest setting. Ring support suggested a reset of the sensor and re-enrolment, I’ve not set the alarm with that sensor active since, but have kept an eye on the logs. I see it’s triggered every day at least once, when nobody was in the room. HELP! Is it never going to work in a conservatory? I’d say that makes it unfit for purpose, and why does the app allow you to select conservatory from the list of install locations? I hope it’s a fault with this sensor??? Thanks in advance.
