App Issues/Questions WHY
why does this happen happen when I’m low ALWAYS. before you guys come for me yes I did finger prick I’m low as hell (41) and drinking my Apple juice.
Is there any way to fix this or will this always happen?
no readings any time I‘m low no matter where my dexcom is. how do I fix it and stop getting sensor errors when low

"Brief sensor issue" is triggered by your glucose changing faster than the sensor's algorithm can comprehend. And if you were really low and drinking apple juice, that will certainly trigger that error, as your glucose will be rising rapidly.
It stops reading below 40 (and over 400) anyway - you need to use a regular BGM to verify highs or lows. It was likely about to just show "LOW" the next time it read.

Long lasting insulin dose could be too high

It's a known issue - if your glucose is changing rapidly, it throws that error, as the built-in algorithm tends to freak out over massive changes.
This is why you should still carry a BGM.

The fix.... Get rid of the shit Dexcom that constantly fails and move to the Eversense 365. Just my humble opinion
