Freestyle libre sensors failing

So for the past few months I've had issues with the sensors simply falling off at night or even while sitting at my desk.

So I went and bought some Tegaderm, since I remember it working very well, to keep them in place. Now that I've put a new one on my arm,and the Tegaderm on top of it, it failed immediately, didn't even provide a single reading but kept asking me to rescan in 10 minutes for a while before finally automatically disabling the sensor.

I've googled what people are using before buying the Tegaderm and many people seem to use it, yet I'm curious if that could've been the issue.
