Sense screen is unresponsive even after trying to troubleshoot it

[smrupert]

(1) My Fitbit Sense (firmware 44.128.5.49) is tracking data and also continues to sync properly; however, the display has stopped responding to touch of any sort (can't swipe in any direction, nor tap). In attempting to remedy, I've reset the device multiple times over several days; after each reset, the clock face reliably appears but the display remains locked to any and all touch. I use an SPO2 clock face, so I attempted loading a standard face to see if that helped--it didn't. In addition to trying this (and the described multiple resets), I've tried restarting my phone (Google Pixel 2XL) as well as turning Bluetooth off and on, also to no avail. (2) During this same period, the device has begun randomly lighting up in the wee hours of my sleep, presumably due to wrist movement (an activation that does not occur during the day and which I do not have designated in my device settings). Further, when this unwanted nighttime activation occurs, the display shows the Fitbit logo, not the clock face. I typically just go back to sleep and by morning the clock face has inexplicably returned. (3) As of just last night, the device did not track overnight data in its entirety (I went to bed ~12AM but my sleep shows as having begun ~330 AM; it also did not register/report SPO2 data this morning); normally I wouldn't be overly concerned since I know similar glitches can caused by improper band placement, but given the other accumulating issues, I have my doubts that this newest development isn't related.

I've had my Sense just 6 weeks, and it's only been within the last week that these problems have arisen.

Did you get your fitbit sense screen to work? If so how? I can not get mine to work.  Thanks Shannon

I'm really upset with fitbit because I didn't purchase the
extended warranty so I'm not eligible for a replacement. But customers
support said it was defective. Is there any chance that I could get a
discount on the purchase of another? Unless you can get me a replacement
because I just purchased my Fitbit Sense in January 2021!! So I have only
had it 9 months. Thank you Shannon Garrison

Fitbit will tell you to factory reset the device, and when that don’t work, offer you a discount on a new device to “keep you in the Fitbit family”, a family of device owners who are having to repurchase their expensive devices every 14 months , conveniently just outside of the warranty period. 
I’ve owned 4 devices now since 2017, and every singe one has crapped out. This time it was a Fitbit sense smart watch which lasted 16 months. I’m done with Fitbit devices, the ridiculous software and app, google removing key app features and the crap support. Apple just have to sit, do nothing and wait for people to come to them at this point.
