My Dexcom upgrade made me check the rules again

I recently started looking into different Dexcom models and realized that scan and imaging guidance may not be identical across versions.

I was wondering how people keep track of restrictions for different Dexcom generations, especially when moving from an older model to a newer one.

For people who have used Dexcom G6, G7, or newer systems, did you notice differences in the instructions for MRI, CT scans, airport security, or other situations?

I'm interested in how users make sure they are following the correct guidance for the exact device they wear.
