Ava Bracelet

Does anyone know what the average temp range for Ava bracelet should be?

I think when temping orally it's between 97-99 degrees.

My average temps with Ava are 95 or 96. But this last week they dropped down to 92.98 and 93's. The glow up won't let me put a temp in below 95 and FF won't let me do anything below 93. Temps are all taken at the same time. I'm just not sure why they are soooo low
